Over a thousand innocent people have died in the border towns of Mexico this year so that some folks can use harmless drugs...
Every choice a person makes with regards to using 'harmless" drugs should be mindful of the real cost of their choices. That is the proper spiritual context IMO.
On the other hand... hundreds of people at Inbev Brewery lost their jobs because of people stopped drinking beer, which is alcohol(drug). In that case: keep consuming alcohol so people won't lose their jobs.
