The legality of delta 8 THC is too complex a topic. This cannabinoid is affected by various state legislations that differ in different parts of the country, although it’s legal at a federal level.

For different reasons, more and more cannabis users are choosing delta 8 THC, but since it’s legal in several states, many doubt whether it’s legal to buy delta 8 in the state of New Hampshire.

Is Delta 8 Legal in New Hampshire?

According to New Hampshire state law, Delta 8 THC is illegal in the state, although it’s federally legal under the 2018 Farm Bill — as long as it’s entirely hemp-derived.

Federal law states hemp from the plant genus cannabis and all its derivatives extracted from flowers, seeds, leaves, and stems from such mature stalks containing less than 0.3% delta 9 THC on a dry weight basis is legal in all 50 states, including New Hampshire.

Thanks to the 2018 Farm Bill, which created an industrial hemp exception, we can use all parts of the plants to make hemp derived products, including hemp seed oil and CBD-infused products.

Hemp products are also allowed in New Hampshire. However, in 2023, the state made an amendment to its hemp laws that basically banned all delta 8 products.

According to the amendment, hemp-derived products that contain more than 0.3% of all THC forms, be it natural or synthetic, are now prohibited. This includes not just delta 9 but also delta 8, delta 10, and other THC isomers.

Do I Need A Medical Card in New Hampshire To Order Delta 8 THC?

You won’t be able to purchase delta 8 products in New Hampshire, even with a medical marijuana card, since the state restricts the sale and use of psychoactive cannabinoids derived from hemp and marijuana.

However, if you reside in a state that allows delta 8 and similar compounds, know that you don’t need a medical marijuana card to order delta 8 THC online or in-store. Delta 8 THC rests in the same legal context as CBD as of the 2018 Farm Bill. Anybody over the age of 21 can buy hemp products, including hemp derived THC products online.

The only restrictions are delta 8 THC products made from marijuana or a cannabis plant that contain more than 0.3% delta 9 THC.

In 2013, New Hampshire was the 19th state to legalize medical marijuana under House Bill 573 [1].

To obtain a medical marijuana charter in New Hampshire, you’ll need to get an evaluation from your primary care physician. In addition, you’ll need your primary care physician to provide you with a certification that you’ll need to submit as an application for the Therapeutic Cannabis Program.

If your application is approved, you’ll receive your card.

As for recreational marijuana in New Hampshire, marijuana remains illegal under the state’s Controlled Drug Act. New Hampshire state law doesn’t allow adult use, including marijuana cultivation.

What’s The Difference Between Delta 8 THC & Delta 9 THC?

The differences between these two cannabinoid analogs begin at the chemical level. Delta 8 THC contains a double bond on the eighth carbon chain, while delta 9 contains the double bond on the ninth.

A hemp or marijuana plant usually contains less than 1% delta 8 THC. In comparison, today’s marijuana plants usually have percentages of delta 9 around 15-20%, reaching up to 30% or more in the most potent strains.

The effects also mark the difference between these two cannabinoids. Delta 8 usually generates a more calming experience. There won’t be any racing thoughts, and anxiousness isn’t a commonly reported side-effect.

The potency of delta 8 THC is about 50% of delta 9 THC, so you’ll need to take a higher dose to get the same intensity of effects.

Delta 8 THC Tinctures

Delta 8 THC tinctures can consume both orally and sublingually. These are usually made from alcohol, as this is the most practical and economical way to manufacture them, but there are also some water-based tinctures (nano-emulsions). But at Area 52, we use MCT oil in our D8-infused tinctures for better absorption when you hold the tincture under your tongue for 30 seconds.

Is Delta 10 THC Legal in New Hampshire?

Delta 10 THC is also illegal in New Hampshire.

This cannabinoid is an isomer of THC that occurs in concentrations below 1% in marijuana and hemp plants. Its effects are similar to those of delta 8 THC. The main difference is that delta 10 provides stronger energetic or stimulating effects than delta 8 THC.

Until not too long ago, delta 10 THC was an unknown cannabinoid. Then, Fusion Farms, a company that manufactures marijuana products, ordered a large order of marijuana from California, where the fires were raging at the time.

After processing the marijuana to extract the cannabinoids as they used to do, they were surprised with the final result: crystals that looked like none they’d seen before.

According to the analysis, the molecular profile of this cannabinoid was similar to that of CBC, but the appearance was very different. After a lot of hard scientific work, the scientists concluded that it was delta 10 THC.

Nowadays, the companies that produce delta 10 do it with food-grade and completely safe methods.
