In 20+ years of prescribing Accutane, I haven't seen any hair loss I could attribute to the drug. Hair loss from Accutane is generally reversible anyway. Minoxidil won't affect the drug, which works very well on acne of the back, as it does on the face. I'm not aware of any interaction with marijuana.
I think you'll be fine.
If you continue to be concerned about genetic hair loss, you may at some point want to look into oral Propecia. Ask your dermatologist.
Take care.

I was part of the experimental trials years back in high school and experienced SIGNIFICANT hair loss that really freaked me out. About two months into treatment my hair was falling out in clumps in the shower and when I brushed my hair. My dermatologist at the time denied that it was related, but it stopped shortly after I stopped taking Accutane. (I'm a girl). My hair was much thinner than it had been before, but really only noticable to me until it started to grow back and I had little tiny hairs all over the place. pretty silly looking. ;) This regrowth continued for years, and every hairdresser I ever had commented on it. I went through a second course of treatment in college, and the SAME thing happened.
I understand from the literature that it is SO rare a side effect that it is not really yet considered to be important, but to me, the coincidence is striking. While your hair loss *may* be related to genetics etc, it is (IMHO) possible that it is also related to Accutane. I am now 8 years post Accutane, and am just recently getting my hair back to what it once was. I don't think it is an immediately reversible side effect, and was quite a painful one for me.
As a matter of fact, I still have acne. Grrrr.... It's not as bad as it once was, but I definitely still get cystic acne.
On a side note, I think it's important to consider that the 'mental' effects of Accutane were only beginning to be discussed during my second course of treatment, and were denied. In reading the stuff on-line today, I see that Depression and Anxiety side effects are now listed as the second most serious possible side effect.
hmmm....
