Does drugs stunt penis growth?

[longgone]

Hi. im 17 and i should have asked earlier... i had my gf all over my penis and she said it looks like its undergrown.. stuff that should be bigger isnt bigger and i was wondering if drugs can do it... since grade 6 ive been smoking weed every day, since grade 9 ive been smoking ciggs every day. i also have done lots of exstacy (not for 2 years now) i have done a fair amount of coke, oxy cotton, seriquel, mdma, some roids, and lots of other stuff. when i was younger i remember it being bigger compaired to my body but now it isnt? some parts seem undeveloped but i have hair, testicals, all the normal stuff. i also am underweight due to these drugs and maybe since im underweight by alot.. i also work out and have a fast matabolism to? i do eat alot when i smoke weed like alot alot more them my friends that weigh 50 pounds more then me. this week i have been quiting weed for my gf and i have lost 13 pounds in one week due to my appetite loss from weed. any way i can gett my body back on track and growing? i used to weigh 130 at one time, i now weigh 107. im 5'10
