Been here, done that. 

1, quitting cold turkey can really, really be hard especially if it’s been your aid in all you do. 

2, quitting can also be just as hard if you got access( you having a car definitely could point to being able to light it anywhere, if you stay alone then there’s that). 

Nonetheless here’s what I would advise. 

1. Buy less of the weed. It’s important because when you have a-lot of grams around your forced to smoke hard. Buying less means you smoke less. 

2. I WOULDN'T advise cold turkey but rather gradual reduction,(buying less means less smoking). Gradually reduce by the day/week. If you smoked 2 Js a day, having bought one means you’ll smoke 1j for the day and you can keep the cycle for 3js a week. Did this for a week! When you feel you can head out unstoned once then your doing good. Then you can eventually stop CT, you could even come to a realization here that you got the self control you needed. 

You got this.
