despite some people saying that there is know such thing as cannabis withdrawl, if you smoke enough for long enough you will have withdrawl proplems that could include sleep problems, being easily irritated, poor appertite and other problems. but trust me go without weed for as long as you can and when you finally decide to get stonned again, youall be completely mashed! plus if you can keep yer toking only to the weekends at most then youall look forward to getting mashed, even more than usall. something i notice is that if i dont have the weed its harder to go without the weed than if i did have the weed.
