In Jainism, alcohol is not allowed at all.

Simple reasons:

1. It makes the mind dull

- Alcohol clouds thinking and reduces self‑control. - Jain Dharma wants a clear, alert mind for ahimsa, prarthana, meditation and good conduct. ( jainknowledge.com)

1. It can lead to himsa (violence)

- When people are drunk, they may hurt others with words or actions, drive carelessly, or behave badly. - This goes directly against ahimsa, the main principle of Jainism. ( jainknowledge.com)

1. It increases bad karma

- Wrong thoughts, speech and actions done under intoxication bind heavy karma and slow down spiritual progress. ( jainknowledge.com)

1. It involves killing tiny living beings

- Alcohol is usually made by fermentation, which uses countless microorganisms (yeast, etc.). - For Jains, these are also jivas (living beings), so making and drinking alcohol means violence to many lives. ( jainknowledge.com)

1. Same rule in both traditions

- Both Digambar and Shwetambar Jains clearly say: intoxicants (madya), including alcohol, are to be completely avoided by followers. ( jainknowledge.com)
