In Jain Dharma, intoxicants and recreational drugs are generally not permitted because they disturb self-control, awareness, and ahimsa.

Jain conduct teaches:

• Avoid intoxication
• Avoid addiction and harmful habits
• Stay mindful and disciplined

For medical necessity, if a medicine is prescribed by a doctor, it is treated differently from recreational drug use.

So, in simple words: Jain people should not use drugs for pleasure or intoxication.
