identifying mold.

im having a huge problem around here lately. everything seems moldy from mids to headies. i see so many posts on these boards about mold. it seems like it would be helpful if anyone who could help people identify mold on there bud could post about what to look for. visually or the smell of the bud. i bought some beasters the other day because i was desperate and there's cat like hairs in the bud. is this mold? the day after i picked up somke outdoors that smell and look wonderfull but when i was breaking up the first bud there was like fucking cotton inside. im really bummed out about wasting all this money and would like to atleast know if i can hit those shitty beasters a few times to help myself sleep. this is the longest i've went without smoking in 3 years, but i guess it beats a lung infection. help me out.
