What didn't I smoke would be easier lol...
I started with cigarettes, which my favorite brands were Camel, Camel Special Lights, and occasionally Marlboros.
I then tried to dampen my cigarette smoking with pipe smoking. I found pipes get nasty and were very hard to maintain-- they always seemed to have a 'gurgle' that I could only get rid of for small amounts of time. I loved pipe tobacco more than anything, but just couldn't get it 'right'.
I've just resigned that I'll forever be a fan of nicotine, but vaping is the only safe and economical way to consume it. To top that, it's quite enjoyable.
