As the cannabis industry grows throughout the U.S., states are introducing rules and laws to govern growth, sales, and processing. The State of New York has now legalized marijuana production and use and established the Office of Cannabis Management to oversee recreational and medical marijuana cultivation, processing, distribution, and retail sale. Long Island’s Nassau County permits marijuana manufacturing and processing.  Theoretically, retail sale is allowed; however, all but a small number of Nassau county jurisdictions have opted out of retail cannabis sales. 

Nassau County Cannabis Guidelines


New York allows the cultivation of cannabis in Nassau County under the Marijuana Regulation and Taxation Act (MRTA). Cultivation can be done at home with a total of 6 marijuana plants (3 mature and 3 immature). Individuals must be at least 21 years old and be using cannabis privately within their homes, and the plants must not be publicly visible.

Manufacturing or processing cannabis-based products is also allowed in Nassau County. There are rules governing what types of cannabis products are and are not allowed, processes that may be used, and the types of packaging that must be used. 

Retail & Delivery

Local city and town municipal authorities in Nassau County have the right to deny or permit retail marijuana businesses in their jurisdictions. This means communities can opt out of permitting retail cannabis organizations to prohibit the sale of adult-use marijuana. Retail marijuana establishments are permitted in areas where authorities have not opted out. Almost all of Nassau County has opted out of retail; however, cultivation and processing are still permitted.

Additionally, cannabis delivery is legalized in the State of New York. Local authorities may not prohibit the delivery of marijuana products into their jurisdiction, regardless of their standing on retail sales.
