Marijuana is less harmful than both alcohol and tobacco. That isn’t something drug dealers or liberals made up, that is established and documented fact. If alcohol and tobacco are legal, but more harmful, why should marijuana be illegal, even though it is less harmful?
QUOTE]
The amount of Tar in one marijuana cigarette is equal to 5 tobacco cigarettes so I would not say that it less harmful.
This claim needs some specifics as to what controls are being placed on the test to ensure a good set of data from which to make this determination that one joint is equal in tar content to one “tobacco cigarette”:
Are we talking about a joint that is equal in every way to a tobacco cigarette in terms of kind, size and weight of paper, length and thickness of the cigarettes, the presence or absence of a filter, and the weight of the contents?
What is the potency of the marijuana being used in the test?
What methodology was used to determine the tar content of the cigarettes?
What was ignored in the data set and what was considered?
What is the definition of tar? Is it biased in any way with respect to one agent over another?
Finally, does the claim take into account that a joint is not smoked the same way a tobacco cigarette is smoked? There are two things to consider here: Firstly, a joint is usually passed around a small (or large) group of people while a tobacco cigarette is usually smoked by one person, resulting in far less smoke being consumed by one person from a single cigarette? Secondly, once the desired effect is obtained from the weed, one stops but the same is not true for tobacco as it has no discernible effect to one accustomed to the smoker, so one would smoke less marijuana than tobacco overall, assuming one smoked both.
There are lots of ways to conduct an experiment. The question is, are you trying to find out the facts or prove a hypothesis?
