how r u going to grow a plant to 10foot under ur bed dude? lol thats funny.....
growing at home is easy... r ur parents clever? do they know what weed smells like? do they own their house? would they care if u did it?
of course u can cut a lead off and smoke it, will it do anything...... hmmmm probably not. might give u headache.
just do it man.......... if u want to, just go for it.
