What is the difference between psychoactive and psychedelic




















The concept of dietary microdosing is potentially important because it points out two areas that deserve investigation but which have been neglected by the academic scientific community: First, I suggest that the potential psychological and psychiatric impact of dietary ingredients may be larger than previously appreciated, particularly when they are combined in specific ways. Many spices and medicinal plants have been studied individually in antidepressant assays and clinical studies but not, to my knowledge, as synergistic combinations.

Apart from studying curcumin as an add-on therapy [e. Second, it appears to be likely that dietary ingredients can modulate the affect the peak, duration, or quality of the experience produced by psychoactive drugs [including, but not limited to, cannabis and psychedelic drugs 41 ].

I suggest that this topic is worth studying within the realm of psychiatric neuroscience rather than remaining in the purview of self-experimentation by enthusiasts 25 , The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Effects of psychedelics There is no safe level of drug use. Psychedelics affect everyone differently, based on: size, weight and health whether the person is used to taking it whether other drugs are taken around the same time the amount taken the strength of the drug varies from batch to batch.

Using psychedelics with other drugs The effects of mixing psychedelics with other drugs, including alcohol, prescription medications and over-the-counter medicines, are often unpredictable.

Health and safety There is no safe way to use psychedelic drugs. It is difficult to predict the strength and effects of psychedelics even if they have been taken before , as the strength and potency can vary from batch to batch. People with mental health conditions or a family history of these conditions should avoid using psychedelics. Taking psychedelics in a familiar environment in the company of people who are known and trusted may alleviate any unpleasant emotional effects.

Anxiety can be counteracted by taking deep, regular breaths while sitting down. Dependence and tolerance Most psychedelics produce tolerance rapidly and psychological dependence can occur in some people. Path2Help Not sure what you are looking for?
