Anyone delving into psychedelic or MDMA-informed guidance quickly encounters a tension: is a guide primarily “scientific” and protocol-oriented, or rather “spiritual” and meaning-oriented? In practice, this dichotomy often proves too simplistic. The question surrounding Marcel van der Putten, known from Triptherapie, is a good example of this. Based on public information and a forum response, the perception is primarily holistic and pragmatic, with attention to biochemistry and psychology, as well as room for personal experience, meaning, and spiritual language.

In this article, we outline how to interpret such profiles, the nuances involved, and how, as a client, you can ask meaningful questions about safety, approach, and expectations. Throughout, we distinguish between what is relevant in scientific research, anecdotal evidence, and practical information.

Why “scientific or spiritual” is often a false choice

Many people seek something to hold onto. For some, “scientific” feels safe and controllable. For others, “spiritual” feels human, enriching, and aligned with inner processes. However, guidance regarding altered states of consciousness and intensive therapy sessions often touches multiple layers simultaneously: body, emotions, memories, relationships, and worldview.

Therefore, a hybrid style frequently emerges in practice: a support worker may simultaneously focus on preparation, contraindications, and integration, while also using words such as connection, meaning, or awareness. This is not inherently inconsistent. On the contrary, it may be an attempt to take seriously both measurable factors (such as sleep, stress, substance use, and setting) and difficult-to-measure factors (such as trust, existential questions, and personal values).

What “scientifically oriented” does and does not mean here

The source description reveals that Marcel presents himself with a background in chemistry and biochemistry, and that he reads extensively on subjects such as health, psychology, nutrition, lifestyle, and well-being. A working method is also mentioned that includes elements such as an intake, discussing medical history and contraindications, and attention to integration. This sounds “scientifically organized” in the sense that there is structure, and that biology and behavior play a role in his way of thinking.

At the same time, it is important to keep terminology clear. “Scientifically oriented” is not the same as “academic researcher”. The forum response also clarifies this: there is no publicly verifiable indication that Marcel himself publishes peer-reviewed research or is affiliated with an institution as a university researcher. This does not mean that his knowledge is inherently unreliable, but rather that it should not be confused with clinical evidence or formal research roles.

A practical way to approach this is to ask what someone is basing their conclusions on. Are they guidelines from studies, practical experience, protocols from training courses, or their own observations? These sources can complement each other, but they should not be lumped together.

The spiritual layer: language for meaning, not necessarily dogma

According to the forum response, Marcel also uses spiritual or existential language, for example regarding connection, the subconscious, “healing,” nature, the universe or God, and concepts such as co-creation. Such words can help people interpret experiences that feel emotionally or existentially profound. In that respect, spirituality can be a “layer of meaning”: a way of talking about values, grief, forgiveness, identity, and direction in life.

It is important to distinguish between open, experiential spirituality and dogmatic spirituality. The picture that emerges from the source is flexible and experiential rather than strictly religious. This can be pleasant for clients, but it can also cause friction if you prefer down-to-earth language. This is not a judgment of right or wrong, but a question of matching: do the vocabulary and attitude align with what you need?

It helps to discuss in advance which interpretive frameworks someone uses. Are insights translated primarily psychologically (emotions, patterns, memory), or also spiritually (meaning, “energy”, universe)? And is there room for the client to choose their own position within this?

Holistic-pragmatic: what does that mean concretely in therapy?

The term “holistic” is often used but can remain vague. In this context, it seems to involve combining multiple domains: biochemistry, lifestyle, psychology, preparation, guidance during the session, and integration afterward. “Pragmatic” suggests that the approach is not primarily ceremonial, but focused on what works practically for the client, within the bounds of safety and feasibility.

In concrete terms, this could mean, for example, paying attention to sleep and stress in the week leading up to the session, reducing risk factors (such as combining with other substances), providing a quiet setting, and having a plan to translate insights into behavior or choices afterward. Such factors are consistent with harm reduction: minimizing risks, optimizing the context, and taking aftercare seriously.

At the same time, it remains essential to acknowledge that “holistic” is no guarantee of an outcome. Experiences can be profound, but also confusing or emotionally intense. The quality of guidance, personal history, and the setting can have a significant influence. Therefore, transparency regarding boundaries and expectations is more important than fancy terms.

Safety and harm reduction: the foundation of every session

Safety and risk mitigation play a major role with substances like MDMA and during psychedelic sessions. This concerns not only physical risks but also psychological safety: how do you deal with anxiety, flashbacks, overwhelm, shame, or dissociation? And is there a plan for aftercare if the effects persist?

In broad terms, harm reduction means remaining realistic about risks, not romanticizing them, and taking practical measures to limit harm. Think of clear screening, discussing contraindications, avoiding dangerous combinations, a safe setting, good support, and integration. It also means acknowledging that not everyone is a good candidate for an intense session, and that postponing or foregoing is sometimes the wisest choice.

Moreover, specifically regarding MDMA, it is relevant to note that sessions are currently not freely available as regular therapy. In the Netherlands, MDMA sessions can currently only take place within scientific research or be discussed in practice in a harm-reduction context. This calls for extra care regarding how people inform themselves and which claims are or are not made.

Trauma, therapy, and expectations: nuance is not a weakness

Much interest in MDMA and psychedelic support stems from the hope of relief from trauma or persistent symptoms. Scientific research explores this subject, but study results are not an individual predictor. A session can evoke feelings of connection or self-compassion, but it can also trigger difficult memories. And even when someone has a meaningful experience, translating it into daily life is often the real work.

A nuanced counselor will therefore usually be cautious about making grand promises. Not because “nothing is possible,” but because it is fairer to acknowledge uncertainty. Especially in cases of trauma, it is important that the counseling focuses not only on the peak experience, but also on stability, boundaries, support, and preventing re-traumatization.

When seeking information on this topic, it can be helpful to view the concept of therapy broadly: not only the session itself, but also preparation, integration, and any additional support. In addition, it is wise to ask how someone handles difficult reactions, what aftercare is available, and when referrals are made.

How do you assess the “match” with a supervisor?

Whether someone is more scientifically or spiritually inclined says little in itself about quality. The match often lies in more concrete questions. Below are examples of questions you can ask without immediately having to think in terms of labels:

Question regarding structure: What do the intake and preparation look like, and what information is included in the assessment?

Safety question: How are risks discussed, and what happens if the session becomes too emotionally intense?

Question regarding language and interpretation: Is an experience explained psychologically, spiritually, or both, and do you have freedom of choice in this?

Question regarding integration: What support is available afterwards to translate insights into behavior and boundaries in daily life?

Question regarding transparency: Which components are based on research, which on practical experience, and what is primarily personal vision?

Whoever asks these questions often notices naturally whether someone is primarily protocol-driven, works mainly ceremonially, or employs a holistic mix. That is generally more informative than a score on “scientific” or “spiritual”.

About the source: what can we and cannot verify?

The information in this article is based on a public forum response and the impressions of public profiles described therein. Such a source is useful for painting a picture, but it has limitations. Some details cannot be independently verified and may change over time. Furthermore, numbers and personal data often remain difficult to verify in such a context. Therefore, it is wise to view this type of information as a starting point for your own questions, not as a definitive assessment.

Anyone who wants to read the original forum answer can do so via this source page. Read it primarily as an interpretation and not as a scientific qualification.

Conclusion

The question of whether Marcel van der Putten is more scientifically or spiritually inclined seems best answered with: both, but in a pragmatic, holistic way. The profile that emerges from the source combines biochemical and psychological interest with experiential and sometimes spiritual language, without clearly reflecting a strictly academic research position.

For clients, it is often most helpful to look beyond the label and ask about the approach, safety, integration, and boundaries. Furthermore, with MDMA, sessions can currently only be discussed within the framework of scientific research or in practice via harm reduction. Anyone wishing to explore the possibility of a conversation or intake can, if that feels appropriate, find more information via sign up for an MDMA session.
