I had previously used adderral, and was seeking an alternative that wouldn't require a prescription. I used nicotine patches for 3 years, before switching to vaporizing for 2 years now, almost entirely because of the socialization it has allowed that patches did not.
I'm sure there's more adverse effects from vaping than patches, and I'm sure long term stimulant use of any sort (caffeine included) can cause problems of many sorts. I personally don't think adderall or other prescription drugs (or unmedicated as I had been most of my life) would have been better, but of course they could have been.
So just wanted to share my experience.
