The potential for addiction to microdosing capsules, which commonly contain psychedelics like LSD or psilocybin, is normally considered to be low. Psychedelics are not known to be addictive in the same way substances like opioids or nicotine are. They don't tend to cause the compulsive use behaviours associated with addiction, partly because they don't trigger the same kind of dopamine release in the brain's reward pathways.
However, approach microdosing with caution. While physical dependency is unlikely, there's a risk of psychological dependency, especially if someone is using microdosing as a way to escape problems or is heavily relying on it for performance enhancement in work or creativity. Like any substance, the context of use and the individual's relationship with it are important factors in determining dependency risk.
