Free Marijuana

H.R. 5843, The Act to Remove Federal Penalties for the Personal Use of Marijuana by Responsible Adults.
Prohibits the imposition of any penalty under an Act of Congress for the possession of marijuana for personal use or for the not-for-profit transfer between adults of marijuana for personal use.

Deems the possession of 100 grams or less of marijuana as personal use (one ounce or less for a not-for-profit transfer between adults).

Allows the imposition of a civil penalty under the Controlled Substances Act for the public use of marijuana if such penalty does not exceed $100.

In principle it is like the use of tobacco.
If people are stupid enough to ruin their health, why should somebody prevent it?
