Buddhism

If you're sick and need medication, take it. You can't meditate your way out of bipolar disorder and it will ruin your life if you try.

The medication is a lot less damaging to the practice than the illness is.

What a lot of people do find is that recreational substances get in the way of deep meditation, which is why they aren't recommended. However there is no absolute prohibition against them. Stuff that makes you as normal as any of us are likely to get isn't in the category of recreational drugs.

So do what you're meant to do in this life and don't let anybody "should" on you about not taking medication you need and they don't.
