1. Use incense/candles while you toke. Burn them while you aren't toking so your parents get used to the idea of you burning them.

2. When you do smoke, make a doob tube. A toilet paper roll stuffed with dryer sheets is all that you need. Exhale your hits into the doob tube.

3. When you are smoking, have a window open with a fan blowing out. I usually exhale through the doob tube and into the back of the fan, blowing the smoke out of the house.

4. Find something (a penny works wonders) to put on the bowl when you've just taken a hit, so that the smoke won't be rising off the bowl and making your room smell.

5. Use eye drops. My personal favorite are Visine intensive care with redness relief. They work like a charm, though they are slightly on the expensive side.

6. Don't play your music/TV loud when you are toking, that will just give your parents reason to come up and investigate.

7. When you are done, spray some Ozium or Febreeze. Don't go overboard, the stuff smells pretty strongly and you don't want your 'rents to get suspicious.

8. When smoking, put a towel under the door. This prevents any smells from getting into the rest of your house.

9. A pleasurable way to smoke inside your house is to turn on your shower, turn on the fan, put a towel under the door, smoke real quick, and hop in the shower and wash. The smells of the shampoo/soap/body wash should supress the smell of the bud, and there's less fabrics in the bathroom, which is what odors like bud stick to the best.

10. Find a good hiding spot. My personal favorite when I still lived with my parents was I could unzip the cover on my futon, and shove anything that I wanted to back there, and it was nearly impossible to see that there was anything out of the ordinary going on.

11. Try not to leave your room for a while after you have smoked in there.

Well, I think that's everything. Good luck!
