it only changes me when i dont have any, my stress levels go throu the roof and i become extremely inpatient. my girlfriend tells me that weed has changed me but i belive that its the lack of weed that actually changes me, i once asked her if she noticed any diffrence in me when i am actually smoking she said no, she thinks that when i am smoking i am happy, more social, and enjoy intelectual conversations but when i am not smoking i am more depressed and anti social. I have used this argument as a good reason for me to start my own grow and supprisingly she said ok =)
