I haven't been drinking for 10 years but used weed, MDMA, amphetamine, shrooms, LSD, and tried some trash a few times in my early 20s (Salvia, DOB, NBOMe). But I had a few bad experiences with psychedelics, and also was frustrated by my older "psychonaut" friends becoming more and more self-absorbed smug assholes, acting like they are enlightened and above all the normies who "don't get it". Personally I wanted to get free from the shitty parts of my mind but I didn't see any real progress from doing drugs.
So I started distancing myself from the psychonaut culture and switched to more traditional methods: meditation and later studying some psychotherapy materials to understand my character. As a result, last year I completely quit smoking weed and don't have desire to use any other drugs anymore. In rare cases when my whole body feels bad due to weather or whatever, I just drop a bit of CBD oil which is not psychoactive.
The happiness and relaxation coming from a clear concentrated mind are supreme to anything drugs can offer through chemistry changes.
