Blah 

A blah is another name for rolled up Cannabis. It is made from the plant Cannabis Sativa. It's intended purpose is for use as a psychoactive (mind-altering) drug.

The main psychoactive ingredient in a blah is THC (delta-9-tetrahydrocannabinol), but more than 400 other chemicals also are in the plant.

Immediate physical effects of a blah include a faster heartbeat and pulse rate, bloodshot eyes, and a dry mouth and throat.

A blah is normally made by taking a cigarette and replacing out the tobacco with cannabis. A blah can also be made by using rolling paper and a filter.

It is common practice to smoke a blah in a group and follows the concept of puff-and-pass.

1. That blah got me so high!

2. Yesterday, i smoked a blah with my friends.

3. We took the weed out the blah and put it in the pipe instead.

A blah is a non-descript, boring, often stupid person that no one pays much attention to. Could be someone sitting right next to you at a restaurant, a bus stop, work, school, etc.

Often thought to be urban legends, but that's just because no one notices them.

1. Having a conversation with a blah like like talking to a rock. Except that the rock is actually kinda cool.

2. Some day the blahs are going to revolt, but nobody will care.

3. Have you ever seen a picture of a blah? Neither have I.
