Short answer: No. Jains do not use psychedelics.

Reason: Jainism emphasizes self-control (yoga), ahimsa (non-harm), and the purification of karma. Psychedelics are intoxicants that cloud judgment, disrupt mindfulness, and can lead to actions that increase negative karma. Both major Jain traditions—Digambara and Śvetāmbara—advise against intoxicants and emphasize discipline, vow-keeping, and inner clarity. For Jain ascetics, using any mind-altering substance would directly violate their vows; householders are likewise advised to cultivate restraint and avoid substances that impair spiritual progress.

If you’d like, I can point you to specific Jain texts or teachings that discuss restraint, karma, and the avoidance of intoxicants.
