Back in the mid 70s at 2nd job I got in with the very heavy drinking/cigarette smoking clique, & tried to be like them, drink in one hand & cigarette in the other (cough, cough)
So the only time I tried dope I really didn't inhale (cos I didn't like inhaling tobacco) & decided after that one "drag" it was too slow, & I remember thinking that it wasn't doing anything for me & got back to the wine. After a couple of years I decided excessive wine was not a good idea either & moved away from my "friends." Water is delicious & one does not feel unwell the following morning.

A couple of years back in winter I visited a friend who was a very heavy dope smoker & realised getting off the train at my normal station (Sydney's drinking & entertainment area) where police dogs sniffed at people, was probably not a good idea as I reeked of smoke & not just from his combustion fire, so I didn't get the train & walked directly to my street & avoided patrols!!
