Here's everything you need to know:
It is illegal to drive high but...
There are two levels of offense according to a new limit on THC levels in the blood stream. 2 nanograms of THC in your blood qualifies as a low-level offense. If you have more than 5 nanograms of THC in your bloodsteam, you will face heavier chargers including imprisonment for 30 days. According to this website, for context, four puffs of a joint contain about 57 nanograms of THC.
You will be fined $1000
The fine will be the most common punishment for low-level offenses where nothing was damaged and no one was injured.
The police may take a blood sample
If an officer deems that a blood test is required to assess THC levels, they may assign a qualified physician to draw blood.
You can be arrested even after you park your car
If an officer suspects that you have consumed marijuana and operated a vehicle "within the preceding three hours" they may issue a drug test and arrest you.
Driving high and drunk is a more serious crime
Experts believe that driving high and drunk seriously impairs motor and brain function. Drivers who have both alocohol and THC in their blood streams will face a punishment equal to the sum of those prescribed for each offense.
