Your Medical Cannabis Q & A

Question: Does marijuana as a medicine make you unsafe to drive?

Answer: AAA July 2017 magazine stated there is NO evidence that marijuana makes you unsafe to drive.

Drugged driving i.e. driving while intoxicated or driving under the influence is based solely on the presence of cannabis (marijuana) in the body, not your capacity to drive.


This same principal is used to determine that marijuana use caused an accident. The mere presence of cannabis in the body of the driver goes into statistics as having “caused” the accident. Never is a chart shown of nonuse marijuana drivers compared to drivers who tested positive for just marijuana in citations issued or accidents reported. It is always about the presence in any amount.


“High on the Highway” author unknown 4.8.19 states: Many argue that driving while mentally medicated on marijuana isn’t nearly as dangerous as driving drunk. A recent study by the National Highway Safety Administration appears to have confirmed it. After studying the habits of over ten thousand drivers for nearly two years, they found that those who got behind the wheel after smoking marijuana were responsible for “NO significant increased risk of crash involvement”.


A video titled, “Three retired police officers use marijuana for the first time” the officers gave each other the field sobriety and driving range tests before and after consuming marijuana. Much to their surprise they all did best on both tests after consuming marijuana.


People who use marijuana as a medicine in small regular doses claim they drive with more caution, in no rush, no street rage, calm, and better focused.


Most medical marijuana patients use their medicine so they can run errands, hold jobs, and claim to function better than when on prescription drugs.


Under the Arizona Medical Marijuana Act a registered patient can fail a marijuana drug test. They can have marijuana in their body in any amount. Arizona has not set a limit that says below this number you are safe to drive or over this number you are not. This has gone to several Arizona courts and it is repeatedly determined that law enforcement must have clear and convincing evidence that a medical marijuana patient is incapacitated, not solely that metabolites are present.


Marijuana attorneys strongly suggest a registered medical marijuana patient politely decline to take a field sobriety test and demand to be given a blood or urine test. The 14 medical qualifying conditions to obtain a medical marijuana patient card are indicative of a disabled person. Even on their best day they will fail a field sobriety test but now the officer has evidence you are incapacitated.


It is always best to air on the side of caution by using the lowest effective dose prior to driving and remember, if you do have an encounter with law enforcement, be polite to officer friendly.
