You're right--I used to be a tobacco addict, & I quit almost 3 yrs ago (THANK GOD!). When I smoked cigarettes, I averaged about 25 cigarettes a day...& if 2 hours went by & I didn't light up again, my body wouldn't let me ignore the suffering I went through, either.
On the other hand, I enjoy smoking marijuana, & when I do, I will smoke about 1/2 a joint, just enough to get a decent buzz. I'll put it out & smoke the rest of it much later, oftentimes the next day. No addiction, no fuss.
You smoke every day, yet you're not addicted. Wasn't there a Richard Pryor joke based on such a premise?
