@rohrkrepierer I know only few ways but never tried.

1 night in city be stoped by random dealer if you have the luck

2 heard from few people that smoked weed their dealer often sell other types of merchandise.

3 on the internet/darknet where you can online buy drugs and other stuff for crypto or gift cards.

Maybe will try 3 in the future to try my luck with money that I will expect to be scammed.
