I’m aware intoxicants are haram, but overall some intoxicants are MUCH less dangerous for our health than non-intoxicant therapies. To give an example, weed against med pills.

Weed gets you high, but it comes from a natural plant that can help your health. Medicines do not get you high, but they are dangerous for our body.

This being said, can someone prefer consuming drugs that intoxicate you instead of common medicines that can harm us in the long term?

Such comparisons don’t work in Islamic law
Consuming Cannabis is not permissible
