I found ecf when looking for an adapter for a 401 or 408 threaded safe smoke ecig. It was like sucking a milkshake through a straw. I had seen a 510 atty and wanted to use it on the safe smoke. Back then nothing was easy to find on the internet. Quickly abandoned the safe smoke for the 510 atty and those little cartridges than just held a little cotton for about 2 hits Probably tried more than my share of devices along the way. 901 Riva's, ego passthroughs, silver bullets, provape, etc..... I think my ejuice was 12mg or occassionally 18mg. I searched in vain for a juice that tasted like a pall mall cigarette. Closest was freedomsmokeusa pall mall. Had tried an overseas companies ejuice and had gotten grape flavor. Made my lips numb, so down the drain it went. Tobacco was about all the US companies were offering at the time with some cherry types and maybe some vanilla's. Usually had to buy their hardware products in order to get the juice. Found Vapor4life and went with their 808's for a time because they had a variety of different pre-filled cartridges. And on and on.........
Started smoking regularly at about age 14 tho I had been lighting my dad's smokes starting at around age 10 . Smoked for a little over 40 years with periods of quit times throughout my life. I was around 2 to 2 and a half packs a day, with stress days closer to 3 packs.
I did quit on my first attempt with the safe smoke cig-a-like. I was determined and desperate to quit smoking. None of the other products on the market ever worked and I tried them all except Chantix. I didn't think that small deposits of whatever was in Chantix in my brain was too good of an idea. Heck, I still smoked while using a patch. Once I had that Safe Smoke device in hand that was it for me. It was horrible, made my mouth and cheeks sore from trying to get something like a hit, but I just kept trying and buying almost everything I could find. Thankfully, it did get better as the industry progressed and grew.
I knew when I found tanks(actually when they started making them) that I would never return to smoking.
I started DIY my own ejuice when it was easier to obtain nicotine and found that 12mg did the trick for me and I stayed there until last year when I ventured into the bigger sub-ohm tanks. Got really adventurous last year and started to build my own coils.
Sorry for the long post.
