Effects - Some Advice?

[micro_mikey]

Swim is new to smoking and buying weed so has some questions:

-Swim recently started buying 1/8th of an ounce for £XX, swim is guessing its pretty strong as it stinks swims room out and swims freinds can smell it from the other side of the house when he is smoking. Is this good value?

-Swim is not sure he is putting enough weed into his joint, an 1/8th bag tends to last swim around 5 - 6 joints even though swim packs them full of weed.

-Apart from the giggles, mild auditory hallucinations and a buzz, Swim often wants to get more stoned. When swim means stoned, he means off his face unable to do anything stoned. If so how many joints or bowls would swim need and what is the most economic?

-Swim has found that of some weed he gets very alert and anxious, while off other bags swim is very spaced out. Does this mean the weed is laced?

Thanks,
