It has no value whatsoever. None. At least recreational drugs get you properly high, smoking just addicts you to nicotine.
That's not really for you to decide on everyone's behalf mate. Adults are aware of pros and cons of everything and this only harms themselves so they're free (and should be free) to make that choice.
I read on about your posts about lost family members (I too have had this) but again, they were aware and chose that option.
It's nothing more than a control issue and that I do not agree with, whether it's in relation to cigarettes, marijuana or whatever. Anything that can lead to danger to others then fair enough but it's highly hypocritical to enforce these whilst having very lax laws around alcohol intake.
