cannabis weakens growth of beard?

cannabis weakens growth of beard?

i know this must be very stupid thread but i remember reading this from some official site. i will try and find it probably it was in
http://www.erowid.org/plants/cannabis/references/journal/1998_hall_lancet_1/1998_hall_lancet_1.pdf

OR
http://www.erowid.org/plants/cannabis/cannabis_journal.shtml#health

anyone got some information on this? it's not that i realy worry about my beard, but it's kinda interesting

 

i doubt it, i've been smoking weed for a long time and my beard is still growing nice and strong

 

there's some evidence that weed may lower testosterone somewhat.
