Personal Use Limits
"In December 2009, the GOC approved a law that prohibited the possession and consumption of small, "personal," amounts of illegal drugs. However, in August 2011, the Colombian Supreme Court overturned this law, finding that Legislative Act No. 2, 2009, which banned the personal use of drugs, "implies the nullification of fundamental rights, and it represses and sanctions with the severest punishments (imprisonment) the personal decision to abandon one‘s personal health, a choice that corresponds to their own decision and does not infringe on the rights of other members of society." The Supreme Court then set the "personal amount" of drugs at 20 grams of marijuana and 1 gram of cocaine."
