ejaculation that heroin gives when intraduced via needle mixed with mda commonly known as X is nothing. Not trying to give anyone any ideas, but when the big C sez I have 6 months I will be alternating that with speedballs.
Of course all of the above is just conjecture on my part. :-)
On your experience may vary discussion. A dear friend Frank Rising bought a gram of coke every weekend as pussy bait from the middle of world war 2 until the late 1980's. A master thief, assistant of hookers and owner of after hour joints survivor of lung cancer, discovered crack circa 1988. This man was a paragon of ignoring temptations did an 8ball a day until he croaked in 1991. Not a pretty drug.
It is an easy drug to quit. Much like booze if you dont have that first hit off the pipe you dont need a second.
smoking tobacco is more difficult in my uneducated opinion
