The severity of a criminal penalty for drug possession is determined by the type of drug and whether it is possessed for personal use or for sale. Harsher sentences entail charges for manufactured drugs like methamphetamine and controlled substances like cocaine and heroin. Although possession of less than one ounce of marijuana for personal use is no longer a crime, possession of more than an ounce or possession for sale is still a crime. Although the California legislature has reduced possession for personal use of manufactured and controlled substances from felonies to misdemeanors, overzealous government employees will frequently assert that substances were instead possessed for sale when they were really intended for personal use. Additionally, drug seizures are frequently the product of police violations of a Constitutional right to privacy. Due to this overreaching by law enforcement, it is imperative that you get an attorney who is capable of identifying Constitutional abridgments and distinguishing possession for sale from personal use.
