What Do I Need to Know about Marijuana?   Podcasts   Answers all the myths with science and facts.  Is it safe to drive using marijuana?  If it is a medicine, how can it hurt me?  What does marijuana use do to my brain? ....

An alarming finding shows that an estimated 14.8 million drivers report getting behind the wheel within one hour after using marijuana in the past 30 days. The impairing effects of marijuana are usually experienced within the first one to four hours after using the drug.1 And marijuana users who drive high are up to twice as likely to be involved in a crash.2

Here are just a few of the health effects you may want to know:

• Marijuana use directly affects the brain—specifically the parts of the brain responsible for memory, learning, and attention.
• The compounds in marijuana can affect the circulatory system and may increase the risk of heart attacks and strokes.
• Smoking marijuana can lead to a greater risk of bronchitis, cough, and phlegm production.
• Marijuana users are significantly more likely than nonusers to develop chronic mental disorders, including schizophrenia. Schizophrenia is a type of mental illness where people might see or hear things that aren't really there (hallucinations).
• Eating foods or drinking beverages that contain marijuana have some different risks than smoking marijuana, including a greater risk of poisoning.
• About 1 in 10 marijuana users will become addicted. For people who begin using before the age of 18, that number rises to 1 in 6.
• Some research shows that using marijuana while you are pregnant[288 KB] can cause health problems in newborns—including low birth weight and developmental problems.
• Marijuana use can slow your reaction time and ability to make decisions when driving[271 KB].

Detailed Information
. Patients freely share their “medicine” with family and friends, and parents are self-diagnosing, and subsequently dosing their children with high-concentration marijuana products for conditions that may simply not exist (attention-deficit/hyperactivity disorder, anxiety, etc.); or allow their medical cards to expire and continue to grow their own.
The use of marijuana for medical conditions, including pain, needs robust studies, and subsequent products need more regulation and consistency for public consumption. Colorado is an example of the societal effect across a wide spectrum of arenas that comes with rampant cannabis use, particularly in youth use and impaired driving fatalities. The problems Colorado is seeing completely transcend “responsible use” or “marijuana as medicine.” 

If you drive on drugs you are out of your mind.

Fatal crashes involving drivers who recently used marijuana doubled in Washington after the state legalized the drug. Washington was one of the first two states to legalize the recreational use of marijuana, and these findings serve as an eye-opening case study for what other states may experience with road safety after legalizing the drug. 

Analysis of Impaired Drivers - Three years ago, about 19 percent of the samples contained THC, the key ingredient in pot. This year, that percentage is up to 33 percent.  

THC is a large, fat-soluble molecule whose concentration in the blood rapidly drops as it is sequestered into the body’s fat stores, including the brain.  Immediately after smoking a joint, the THC level will be very high in the blood and very low in the brain.  The THC level in the brain climbs rapidly at the same time that as it is declining in the blood.  At some point, the concentrations cross, and the concentration continues to rise in the brain while it is still declining in the blood, since the brain acts like a sponge, soaking up the partially insoluble THC from the blood.  

"But what we've found out is that as alcohol-impaired driving is going down, drug-impaired driving is going up." 

• THC moves more rapidly than alcohol out of the bloodstream and into the body, making it harder to detect accurately with a blood test.
