Humans contain cannabinoid (CB) receptors, which is what enables the psychoactive as well as therapeutic effects of cannabinoids to be felt. CB receptors are in many parts of the body and brain, which is why cannabis can affect a variety of sensations including pain, inflammation, appetite, neurological activity, and mood.

As with alcohol, the effects of cannabis will vary with each person’s body chemistry. This is due in large part to the fact that CB receptors vary from one person to the next, and the quantity of those receptors is not fixed.


Cannabis can only be purchased by people age 21 and older with a valid ID.  Different rules apply for registered medical patients. Here are the legal limits* you can purchase in a single visit:  

  • One ounce of usable marijuana (flower or joints)
  • Seven grams of concentrate/extract for inhalation
  • 16 ounces of solid infused products
  • 72 ounces of liquid infused products
  • no limits on paraphernalia (pipes, lighters, rolling papers etc)

*For medical card holders, the transaction limits are three times these quantities.


Cannabis is legal in Colorado, Oregon and Alaska in addition to Washington, but bringing any Schedule 1 drugs (like cannabis in any form) across state lines is a federal offense.


Although cannabis is legal, opening or consuming any form of it within view of the public is illegal, with a $27 fine in Seattle. Additionally, cannabis smoking is prohibited in certain private areas such as universities, workplaces, and rental properties.


Cannabis can only be purchased legally from a licensed retailer. Recreationally, growing cannabis plants for personal use is still prohibited.


Cannabis impairs reflexes and judgment, like alcohol or some prescription medicines. Enjoy cannabis responsibly and respect the other drivers on the road. Call a friend, rideshare, taxi, or wait until you’re sober. Open container laws apply to cannabis in the same way they apply to alcohol. Keep cannabis products in their original, sealed package in your car.


Companies can still prohibit their employees from cannabis usage, and can still drug test. Read your company’s employee manual to know your rights.



Store your flower bud in a glass jar away from bright lights, moisture and heat to keep it fresh and potent. Use a grinder to minimize handling of the flowers. They’ll burn more uniformly.

  1. Airtight. Pick a container that fits flower quantity without too much extra air. Plastic bags are too permeable and may allow products to get crushed. Materials that keep out extra light are a bonus.
  2. Humidity control. Keep containers free of outside moisture to preserve flavor and potency. Optimum relative humidity is between 59% and 63%.
  3. Cool temp. Ideally, flower should be stored between 40 to 80 degrees F.  While some cannabis-infused edibles hold up well in the freezer, most other cannabis products degrade in freezing temperatures.


Store your cartridge with the mouthpiece upright (a drinking glass works great) and detach it from your pen when not in use. If your cartridge clogs, try blowing into the connector end to clear out accumulated oil.
