For example, marijuana smokers can develop a daily cough or have a higher chance of getting a lung infection. Like tobacco smoke, marijuana smoke has a toxic mix of gases and tiny particles that can harm the lungs. Although we're still learning if marijuana causes lung cancer, many people who smoke marijuana also smoke cigarettes, which do cause cancer.
Also, smoking marijuana can make it harder to quit smoking cigarettes. Some people think that vaping is a safer way to use marijuana because you're not inhaling smoke.
But you're still inhaling various chemicals when using a vaporizer. A study of some vaporizer products found the vapor contains toxic chemicals and possibly toxic metal particles from the device itself.
People who have taken large doses or used marijuana with high THC content may experience brief psychosis. Psychosis can affect the mind and make it hard for a person to understand what's real and what isn't. Some people have a gene that may increase the chance of long-lasting psychotic disorders, such as schizophrenia a severe mental disorder that affects thoughts, feelings, and behavior , when they repeatedly use marijuana.
While there are no reports of someone dying directly from marijuana use, it can still cause serious health problems. Some people have psychotic reactions that can lead to dangerous behaviors. Others may have uncomfortable side effects from marijuana, such as shaking, leading them to seek care in an emergency room. The effects of marijuana usually last from 1 to 3 hours, but marijuana can stay in the body for days or even weeks after use. Organs in the body have fatty tissues that absorb the THC in marijuana.
In general, standard urine tests can detect THC several days after use. In people who use heavily, however, urine tests can sometimes detect THC for several weeks. Research suggests that teens usually try alcohol, tobacco, and marijuana before most other drugs. But most people who use marijuana don't go on to use other drugs. Here are a few theories about why some do:. Some varieties could cause dramatically different effects than the person might expect.
Half typically used concentrates oils, extracts and waxes that include the active ingredients without the leaves and stems. The other half of typically used flower from the plant.. Those who used concentrates had much higher THC levels at all three points, with levels spiking to 1, micrograms per milliliter in the few minutes after use, while flower users spiked at micrograms per milliliter. Previous studies have shown that THC levels hover around to micrograms per milliliter after marijuana use.
But within about an hour, that impairment faded. There may be genetic or biological differences that make some people metabolize THC more quickly. And it may be that once compounds in marijuana, called cannabinoids, fill receptors in the brain that spark intoxication, additional cannabinoids have little impact.
The authors caution that the study examined regular users who have learned to meter their use based on the desired effect, and does not apply to inexperienced users.
Those users should still be extremely cautious with concentrates, said Hutchison. In addition to receiving pre-employment drug screenings for traces of marijuana , cocaine, amphetamines and various other illegal substances, astronauts undergo periodic random drug screenings to satisfy federal regulations and make sure they still have the proverbial right stuff. The topic came up after the reporter asked Tyson his thoughts about billionaire space entrepreneur Elon Musk taking a hit of weed during a recorded interview with TV personality and podcast host Joe Rogan.
Musk, whose spaceflight company SpaceX contracts with the U. Air Force, is reportedly being investigated by Air Force officials for his use of the drug. Do not get high at the expense of social interaction. Do get high with your significant other. Do listen to excellent music and eat excellent food.
