make some cookies and leave them out and she will eat one and then she will see it isnt all that mind altering....i wouldnt do that to my mom but some ppl would.

my mom just found out i smoke but i am 23 and she cant really stop me lol but she came to my apt and saw my gnome grown poster and a stem on the table and she asked me how long id been smoking. i just showed her my stash and my pipe and everything and she was cool with it
