Weed has not been bad for me.
I used to smoke it every day.
Nowadays I'll occasionally pull out the vape machine at the end of a week for a few puffs because it's still the cleanest way of unwinding I know.
Personally when I smoke I don't need anything else. The only adverse affect I suffer is an unnatural hunger for bacon flavoured crisps.
Of course I'm well aware that some people will get 'addicted' to weed and that even the most lenient of studies indicate that it likely impacts cognitive development if ingested regularly earlier in life.
I also worked my way through a coke habit some years back.
It was great fun at the start, no strings attached, no costs either, and it just kept getting better and better.
I'm not sure when exactly it turned bad because it all began to blur but when it did turn bad it got nasty, and even then it took me a while to realized I wasn't in control like I thought I was.
Cocaine is not an honest drug. It lies all the time.
