As someone who is in recovery for drug and alcohol abuse, my own experience disagrees.

Given any choice of substances, I’ll run wild with them.

I can successfully self destruct no matter what the substance. Harming not just myself, but everyone around me as I go.

From a risk assessment standpoint, yes, marijuana has lower physical impacts (you’re not going to seize from withdrawals afaik).

However, the psychological impacts are different to alcohol. Alcohol encourages “release” of emotions. Marijuana closes everything off.

Furthermore, the impact I have on society can be damaging with both, but in different ways.

So, in my own experience, put down both.

It’s a hop, skip and a jump from one heavy night to picking up the beer/spliffs again.
