With the temporary high will come some form of low. Studies show long term use can lead to depression. I'm not going to tell you not to smoke it. You're already weighing up the pros and cons and even if I did hypothetically say don't smoke it, if you really wanted to you probably would. Having it freely available is just a fabricated justification in your mind. Alcohol is freely available but that doesn't mean those who have given up alcohol addiction need to start buying it because it's freely available.

We're all free to make choices. But we are not free of the consequences of our choices.

PS: I smoked that shiuet years ago and it gave me nothing but paranoia, anxiety and distorted thinking.
