Congress is not about to change the law any time soon. In fact, they are ratcheting up the war on drugs. There is a bill (HR 1528) that has been introduced to committees that would make it a crime punishable by a manditory minimum of 2-3 years in prison to fail to snitch on your neighbor if you had knowledge of (or if you could not prove that you did not have knowledge of) them posessing or selling drugs, if they have any persons in their house under the age of 21. Alternatively, you could face a manditory minimum of 5 years in prison for possessing with intent to sell more than 5 grams of MJ within 1000
ft of a drug treatment facility.
