What can I do to safely grow facial hair?

I have a problem. I am a 21-year-old male with the face of a 15-year-old. What I mean is that I am unable to grow facial hair. I was late starting puberty and it has left me underdeveloped. My baby face is affecting people's trust in me, especially at my job. I am constantly referred to as the kid and I feel that I am never really taken seriously. I am wondering if there are any types of drugs that can possibly aid in my facial hair growth problem and, if there are, what are the side effects? Please help me. I am sick of being a man trapped behind a child's face. Thank you in advance.


Does marijuana produce serotonin?

My girlfriend tells me she uses marijuana to calm herself if she is having a stressful day. She has been doing this for many years. She says smoking pot is like self-medicating — it is better than using anti-depressants. She also claims smoking pot helps with depression because of how it helps produce serotonin in the body. What is serotonin and how does it help depression? Does smoking pot really help with managing your anxiety, depression, etc.?


Why am I so itchy?

For about two months now my whole body had been itchy and will sometimes break out into a rash. I tried switching soaps and laundry detergent; I just don't know what it is. It's on my arms, legs, back, inner thighs, feet, etc. I'm scared and really want to find out what's wrong and stop itching.
