In Jain Dharma, using weed is not considered appropriate.

Reason:

• It is an intoxicant, and Jain ethics avoid substances that weaken awareness, self-control, and right conduct.
• Jain life emphasizes ahimsa, discipline, and clarity of mind.
• Anything that increases carelessness, attachment, or harmful behavior is generally avoided.

So, from a Jain perspective, weed should be avoided.

If you want, I can also explain this according to householder vows and monastic conduct in Jainism.
