C'mon. I hope no one is really risking their lungs or health (or maybe even life) by smoking moldy weed. That is just desperate and sad. Throw it out, life is worth more than a $25er. Moldy buds are really dangerous to consume or smoke. Bin them.
If you get some buds that are slightly wet, just get something like a magazine, or a thin tall container if possible and use a hair dryer on low. That's if you're desperate for a smoke. NEVER microwave buds. BAD! You will hardly get stoned. It really does seem to kill a fair bit of THC. Oven on very low should be okay, but I've found just pulling the buds apart a little and dropping them in a wood or cardboard box overnight is fine. Maybe throw some silicon baggies in there (like the ones that come with beef jerky

) They will be good in a day, or maybe a day and a half.
If you're smoking them and theyre still slightly wet, try mixing a bit of tobacco with it, it will help it burn a fair bit. If you're not a fan of evil tobacco, then heat the cone piece/bowl up lots before applying flame to weed and inhaling.
And to address two myths/mis-informations. Penecillin is not synthesized from any mold that grows on marijuana, it's just dangerous. And also, no real dealer will spray their weed (i assume you mean fly spray or something), this does not make the weed more potent and it is highly dangerous. Alot of people say hydro buds that are very harsh to smoke are sprayed by the dealers to get you more "fucked up". This is a bullshit myth, spraying weed is dangerous and it would just make you cough. If your nugs are really harsh, it's because there is either a shit load of resin coated on your buds, or most likely the plant was not flushed before harvested. Meaning your buds have a fair few unknown chemicals in them, that are probably pretty nasty. I hate growers that don't flush!
