K2 can cause increased heart rate, loss of consciousness, paranoia, hallucinations and psychotic episodes. Users report that smoking small amounts results in intense highs comparable to smoking large amounts of marijuana.
Studies in 2008 revealed that users developed chemical dependencies, withdrawal and addictive behaviors. Increasing numbers of children are purchasing synthetic marijuana products because they are legal and easier to obtain than cigarettes.
Because of the various chemicals being used, these substances are difficult to regulate. But the DEA is determining whether some or all of these products need to be controlled. More research is definitely needed. With young people using K2 more, some states are not waiting for the DEA and are moving to ban it.
Let's face it: Anytime you consume an uncontrolled or unregulated drug or a drug with unknown effects, you are taking a risk. Products like K2 are not made in a controlled environment, and those who use it are playing Russian roulette.
Schedule I drugs are defined as substances that have a high potential for abuse and no accepted medical use. At this time, the evidence suggests that these synthetic marijuana substances should be controlled and perhaps classified as Schedule I drugs.
