Ye it’s just one vicious circle.
Normally people I know, and I have aswell. If they have any weed, they smoke this when the coke as run out. It’s to take the edge off the comedown and probably try and get them to sleep. Theres no point in having coke feeling up or off your tits and smoking weed at the same time. There totally opposite drugs. One is and up and the other is a down or relaxer. So weed normally comes after coke. But some do have it together.
I guess it could slow you down and mellow you out so your not as bad from the coke. If this makes sence
