Is Cannabis Legal in Maine?

Cannabis flower and concentrate, two forms of THC that may be available in Maine dispensaries.

Absolutely, in Maine, marijuana enjoys legal status. Both the Marijuana Legalization Act and the Maine Medical Use of Marijuana Act outline the provisions for eligible individuals to utilize marijuana for both medical and recreational purposes. 

The state levies a 15% excise tax on cannabis plantations and a 10% sales tax on retail dispensaries. However, medical cannabis patients are exempt from these taxes. Despite the price hikes due to taxation, the cannabis market continues to flourish. 

It's worth noting that, as a Schedule I controlled substance under the 1970 Controlled Substance Act, federal regulations prohibit marijuana use on federally-owned properties within Maine, even though it's legalized. Additionally, it's illegal to transport any form of marijuana product from Maine to other states.

Regulations for Recreational Use

In Maine, recreational marijuana use is subject to the following regulations:

  • Adults aged 21 and older can buy and possess up to 2.5 ounces of cannabis. This can include a combination of flower, cannabis concentrate, or other cannabis products, but may include no more than 5 grams of cannabis concentrate.
  • Adults aged 21 or older can share up to 2.5 ounces of processed marijuana and six immature cannabis plants or seedlings without any exchange of payment.
  • They're also allowed to cultivate up to twelve immature, six mature cannabis plants, and an unlimited number of seedlings.
  • Legal recreational users can travel with limited amounts of cannabis for personal use if stored in a sealed container and out of reach while in the vehicle. It may be placed in the trunk. 
  • Rec users can consume marijuana in private locations, such as their home, and away from public spaces and people under the age of 18. 

Qualifying Conditions and Regulations for Medical Cannabis in Maine

Medical caregivers and patients have their own set of permissions, including:

  • the possession of up to 8 pounds of harvested cannabis
  • cultivation of six mature and twelve immature marijuana plants
  • possession of cannabis paraphernalia. 
  • Sharing up to 2.5 ounces of harvested cannabis with another medical marijuana patient without any financial transactions involved.

Unlike other states, there are no qualifying conditions to qualify a patient for medical marijuana. Instead, physicians can use their discretion to recommend cannabis to patients.
