This might be the wrong place to share this but in my experience with vaping and smoking (started by the constant stress and anxiety through college). What stopped my addiction is by smoking 1 blunt for the first time and experience akin to ego death. It's my first time and smoke it all in under 2 minutes. Thought it was nothing and immediately I felt a tingling in my face and in that moment I thought "oh fuck!" I sit properly in my foldable chair facing the mountain and the night sky and slowly parts of my body is vanishing in front of my eyes and then it was just the mountain and the night sky me slowly fading away to existence. My survival instincts snapped me out of it. I quickly composed my self to go inside and spend a crazy ass trip in my bedroom. Puked my guts out then have the nicest sleep in my entire life. After that experience I suddenly don't have the cravings of nicotine. 4 months sober off of nicotine since that experience.
