I know exactly how hard this can be as I was in-and-out of remission with mary-jew-wanna for too many years to count on my journey here. My closest friends smoke it unfortunately.
I go to karaoke and I put the foot down on myself after struggling financially. I told myself that I can't afford it - alcohol or weed. After quitting, I told all my friends and they were supportive and proud of me. Although it felt like I was giving up my favourite crutch in life I slowly began to appreciate it. Money tends to burn a hole in my pocket and I used to window shop online (it's legal here in Canada and I know of more vendors than I care to admit). It's so easy to fall in this trap, I know.
Some things that make it desireable are:
1.) The temporary feelings of joy and inspiration it brings.
2.) Its endless aromas and compositions.
3.) Connoisseur aspects.
4.) Its social and emotional connections.
Remember that all the above ideas are created in our mind. We have to reprogram our thinking which isn't easy but it's worth it. Realize that it creates holes in your aura and makes you more spiritually open and vulnerable. You may feel like you're more in-touch with the spiritual when high (which is true), however this is a shortcut and a very harmful way to reach a meditative state. Overtime it has physical detriments also. Just look at Seth Rogan for an example. He's overweight, slow-thinking and he constantly has that goofy looking face; the same one you or I may have without even realizing it.
Also consider the many ties cannabis has to Jews. In 1964 Raphael Mechoulam (Jew) was the first to isolate THC. Also, Mezz Mezzrow (Jew) was one of the earliest and most prominent figures in popularizing marijuana in the USA.
Consider also strains like Kosher Kush, Jesus OG, various "God" strains, etc. The former one also was the first commercially available strain to be blessed by a Rabbi. They love this harmful crap.
My advice is to think about the long-term over the short-term. Try improving your eating habits, lifestyle and sleep while meditating every day. Over time you'll start feeling better than marijuana could ever make you feel. Plus you won't be as forgetful, emotional, impatient and so on.
One other little piece of advice (you can seriously take it or leave it) but if you find yourself struggling emotionally and craving it, try listening to Satanic-themed music (a favourite of mine is Archgoat, however they are quite extreme) and try reading through the forums. Also try to cut yourself off from anything that might make you think about it for a while, such as TV or whatever.
Listening to music like that for some reason helps me remember that marijuana is not for Satanists... it's for the weak, and we sir here are not weak, we are Satanists! I believe in you and remember that you can always reach out about any problems you have on these forums. People here understand because we've all experienced so many of these same struggles. You're never alone; you've got the JoS and the Gods at your side. Don't forget that and stay strong brother! It's a blessing we were able to see through the truth of the world and we mustn't squander this opportunity on things that don't develop us or bring us real fulfillment.
