How is marijuana used?
Marijuana is usually smoked or consumed. Marijuana can be smoked in cigarettes (joints), pipes or water pipes (bongs). Marijuana can be consumed in food or drink products called edibles. It can also be used through tinctures, creams or oils. Marijuana smoke has a pungent and distinctive odor, often referred to as both sweet-and-sour or skunky.25
Different forms of marijuana cause effects that can be brief or last for hours. Use caution when driving, biking or performing other safety sensitive activities after use of any form of marijuana, including vaporized products.1
Typical marijuana plants contain more than 400 chemicals, including about 60 that can interact with the body’s nervous system.4 Regular marijuana use (weekly) is associated with depression and may be associated with other mental health disorders like anxiety and psychosis.1 Less is known about the health issues that might be caused by occasional marijuana use. Marijuana also can be contaminated with mold, insecticides or other chemicals. Health effects of many of these chemicals are not known.
Heavy marijuana smoking (daily or near daily) is strongly associated with chronic bronchitis, including chronic cough, sputum production and wheezing.1 Marijuana smoke, both firsthand and secondhand, contains many of the same cancer-causing chemicals as tobacco smoke.1 1
6 This may mean a smoker using a bong may inhale more harmful tars to get the same dose of THC as someone smoking a joint.
Though smoking marijuana has the added risk of harmful smoke exposure, eating or drinking marijuana still exposes you to THC, the chemical that makes you “high.”
The effects from eating or drinking marijuana can last up to 10 hours. This means that someone can be impaired from marijuana for a long time after eating or drinking marijuana.1 Wait at least 8 hours after eating or drinking less than 18mg of THC before driving, biking or performing other safety-sensitive activities. If you have consumed more than 18mg of THC, wait longer.1
state health department's training. The training will help marijuana product manufacturers to learn the basics of safe food handling, similar to the training provided to anyone working in the food industry. This training does not address potency, the effects of cooking or other production methods on potency or the amounts of THC within edible products.
Using alcohol and marijuana at the same time is likely to result in greater impairment than either one alone.1 Use caution when driving, biking or performing any other safety-sensitive activities after use of any form of marijuana, especially if you have also consumed alcohol.Hash oil (also known as butane hash oil, dabs, wax, earwax, honey, honey oil, or shatter) is a product created by extracting THC from the marijuana plant. This product may contain up to 60-80% THC and is consumed by smoking, vaporizing, or adding to food.
Making hash oil using flammable liquids is extremely dangerous. It has resulted in explosions, severe burns and death. There are safer ways to make hash oil. We recommend buying it from a licensed marijuana retail store. If you do choose to make your own, consider using dry ice (CO2) or ice water. These methods reduce the risk of fire and explosion. If using flammables, make sure they are used outdoors and away from sparks, flames or anything else that could start a fire. Evaporation of the flammable liquids should only be performed outdoors. Do NOT use external heat.
negative physical and emotional reactions. Since dabbing only became more common recently, there is no reliable information on long term health effects.
No. Synthetic marijuana, also known as spice or K2, is not a natural product. Chemicals are often sprayed on synthetic marijuana and may cause elevated heart rates and blood pressure, drowsiness, agitation, hallucinations, seizures, tremors (shaking), vomiting, paranoia, loss of physical control, and comas.
