I agree I veered off the parent's point.

In his case his whole life could have been ruined by selling a harmless (if clean!) drug to ravers who very clearly know what and why they are buying a substance from him.

Also, in my hypothetical "you should not have been arrested as it should be legal case" he might have ended poor and homeless in the street because everybody was just going to the pharmacy instead of buying from him. :)
