When making concentrates, extracting cannabis oil with flammable materials, such as propane and butane, is illegal. These materials release vapors that can easily trigger explosions. Consider alternative extraction methods.

Growing cannabis plants indoors often requires high-powered lamps, temperature controls, and expanded levels of ventilation which can overload electrical circuits and cause fires. To lower your risk of electrical fires, consult a licensed electrician to ensure you are following all relevant fire codes.

Public consumption is not allowed
While it is legal to possess cannabis products in public, any consumption of marijuana in public or smoking marijuana in an area where smoking tobacco is prohibited is also in violation of the law. Non-locals might think that Massachusetts residents walk down the street smoking cannabis like tobacco, but that is completely false. Don’t make this mistake and end up with serious consequences.
There are buying limits
There are limits for how much cannabis any person can buy at a time, regardless of whether you are a resident of Massachusetts or not. The current possession limit is one ounce, where not more than five grams of marijuana can be in the form of marijuana concentrate. That can get confusing when you are purchasing different kinds of products in a dispensary. Your budtender and other dispensary staff will be able to help guide you when making purchases to ensure you stay under the legal limit. Keep in mind that they also are prohibited from selling you more than that amount per transaction, so don’t try to convince or coerce them into selling you more. That is illegal and will land everyone involved in hot water.

Have your ID ready
First of all, remember that you have to be 21 to purchase and consume cannabis legally. No exceptions. And there will be no fooling a dispensary or getting by without an official government issued ID the way some people get around the law when it comes to buying alcohol under age. The rules are strict with cannabis sales and your ID will be checked and rechecked before you are allowed into the establishment, let alone to make a purchase.

Not all hotels or other rental accommodations are cool with consumption
For visitors who abide by the “no public consumption” rules, there are only a few options left for them as far as locations to consume their legally purchased cannabis products. While some people may be staying with friends or family in private residences, others will be staying in a hotel or other rental property. Be sure to check with any kind of rental or hotel accommodations before consuming cannabis products – whether by smoking, vaping, eating or otherwise – on their premises. Some property owners or managers are okay with cannabis use, while some are strictly opposed to consumption on their property. Don’t get kicked out of your accommodations because you didn’t follow the rules. Massachusetts currently does not license social consumption or mixed-use establishments such as marijuana consumption bars or yoga studios.
