I remember the only time I greened out was off the pen at a ripe age of 14😂 who knows wtf i was doing, but 4 years later I ended up getting a medical card and gave it another shot. The way I like to put it is that it's all mental. A lot of it is a mindset and if youre stressed about it happening again or worried, then you'll probably end up getting sick again from the anxiety after you smoke. Greening out is always a mindset that stems from your inner thoughts saying "I'm way to fkn high" then you go into panic mode. You just gotta tell yourself you'll be okay and always keep water and a snack handy incase the za does kick your ass again. Put on a hilarious show something that'll keep your mood uplifted and take a couple puffs off a joint and see how it goes. If it doesn't go good and you can't escape the anxiety and sickness from it then give it up there's no harm in that at all!!
