i am 23 years old, physically and mentally fit, i want to grow a long thick dense beard but my beard as of now is a bit patch and to dense it i have stated taking biotin, i do go to gym 6-7 a week, taking proper diet.

but i smoke not that heavily ...sometimes its like i go without smoking for 3-4 days and then i end up smoking 3-4 cig in day....
SO THE BIOTIN I AM TAKING WILL THAT HAVE ANY SIDE EFFECTS COZ OF MY SMOKING.....( I AM TRYING HARD TO QUIT SMOKING BUT YOU KNOW ....FRIENDS)
