Delta-8 THC: A Better and Legal Alternative to Marijuana in Missouri

Delta 8 oil with hemp leaves

Missouri legalized marijuana for medical use in December 2022. However, if you’re after a milder, smoother high, then you might want to check out delta-8 THC.

It’s an alternative psychoactive cannabinoid that’s legal under federal and state laws.

Delta-8 is less potent than delta-9 THC from marijuana; it doesn’t get you as anxious at high doses, and it’s derived from hemp.

Here’s what you need to know about this cannabinoid.

Delta-8 THC vs Delta-9 THC

THC has many variants; the most popular ones are delta-8 THC and delta-9 THC.

Delta-8 THC is the isomer of delta-9, meaning it has a similar chemical formula. However, its atomic bonds are arranged differently, hence the slightly different effect profile.

Delta-8 THC has a double bond at the eighth chain, while delta-9 THC has it at the ninth chain. Because of that, delta-8 is about 50% less potent than delta-9.

Unlike delta-9 THC, delta-8 can be extracted from hemp by converting the CBD molecule.

This makes it federally legal according to the 2018 Farm Bill.

But why would one avoid marijuana for other reasons than potential legal problems?

Cons of Delta-9 THC from Marijuana

Delta-9 THC is a mildly psychedelic compound. Its effects depend on the dose; low and moderate doses elevate your mood, reduce stress, curb pain and inflammation, and may enhance your focus.

Higher doses are intoxicating. You can get high if you take enough THC, which will manifest in euphoria, giggles, increased appetite, sharpened senses, altered thinking patterns, and changes in the perception of your surroundings.

Most people enjoy being high without any unpleasant reactions.

However, some individuals are particularly sensitive to the psychoactive nature of delta-9 THC.

The side effects of taking too much delta-9 include:

  • Anxiety
  • Paranoia
  • Feelings of discomfort
  • Cold sweats
  • Dizziness
  • Confusion
  • Increased heart rate
  • Short-term memory problems

Effects and Benefits of Delta-8 THC

Since delta-8 THC isn’t as powerful as delta-9 THC, it offers a smooth cognitive buzz accompanied by a wave of calmness and a boost of creativity. Depending on the terpene profile of your delta-8 THC product, the effects may lean toward sedating or energizing.

You’d need to consume twice the amount of delta-8 THC to experience a similar type of effects as with delta-9 THC. You can still get anxious, but it’s more difficult. Anyway, I suggest that you use delta-8 extracts responsibly, as with any psychoactive cannabinoid.

People use delta-8 THC for similar health benefits to delta-9 THC, including:

  • Anti-nausea
  • Anti-inflammatory
  • Pain relief
  • Increased appetite
  • Feelings of calmness and relaxation
  • Euphoria
  • Neuroprotection

Is Delta-8 THC Legal in Missouri?

Yes. Delta-8 THC is federally legal under Missouri law. The state regulations align with the 2018 Farm Bill, which legalized hemp and all its derivatives by removing them from the list of controlled substances.

As long as the end product contains no more than 0.3% delta-9 THC on a dry weight basis, you can legally buy it in Missouri’s local and online stores.

Benefits of Buying Delta-8 THC Online

Buying delta-8 THC online comes with three main perks:

  • Lower prices: unlike stationery vendors, online stores can cut out the middleman, which translates into lower prices. You can further save even more money by joining a reward program, choosing subscription orders, or using a special coupon code.
  • Higher transparency: when you buy delta-8 THC locally, you need to rely solely on the store owner’s perception of what’s a high-quality product and what’s not. Shopping for delta-8 THC online gives you more tools for researching your potential supplier. You can look into the certificates of analysis (CoAs), comb through customer reviews, read the company’s “About Us” section, or search Reddit and social media groups for threads about the brand.
  • Convenience: you can compare hundreds of different products in the comfort of your home, at any time you want — even when it’s 2 AM and you’re sitting there in your pajamas. It’s a huge time saver. Of course, you’ll need to wait the extra 2-3 days for delivery, but you can rest assured you’re getting a certified product that will be both safe and effective.

Best Online Delta-8 THC Stores in Missouri

Finding a trustworthy delta-8 THC store can be challenging, especially if you’re just soaking your feet in the delta-8 space.

If you don’t have the time to read user reviews and analyze lab reports, here’s a quick recommendation from me. These are the two leading brands whose products I’ve been using for the last two years with great results. Both companies excel at integrity, transparency, and product quality.

1. Area 52

Get 15% off all Area 52 products. Use code “CFAH” at checkout.

Area 52 is a Nevada-based brand that offers various delta-8 THC extracts from pure distillate.

You can choose from tinctures, vapes, edibles, and pre-rolled joints infused with decent doses of delta-8 (25-40 mg per serving) and rich in terpenes — leveraging the whole-plant synergy in cannabis.

Unlike many brands on the market, Area 52 doesn’t use hazardous chemicals during extraction, and its products are thoroughly tested in an ISO-certified laboratory for potency and contaminants, including pesticides, heavy metals, solvents, and mold.

Recently, Area52 released a new line of “true full-spectrum” products, featuring innovative formats like delta-8 honey and HHC gummies, as well as traditional products such as CBG energy gummies, CBN sleep gummies, immunity gummies, and CBD oil.

2. Finest Labs

Finest Labs’ product range includes delta-8 THC tinctures, gummies, and vape carts. You can also choose from HHC gummies and energy gummies infused with Vitamin B12.

Can you grow weed in Missouri?

With the law amendment, residents of Missouri are allowed to grow up to six cannabis plants without public view.

Missouri also allows shared cultivation. This means that a maximum of two patients may cultivate in the same space.

Can you smoke marijuana in public?

Medical marijuana patients are prohibited from using it in public places, including parks, sidewalks, schools, churches, and businesses.

According to the law, “for purposes of designating a non-public place within a public place, the owner or entity of any such property may, but is not required to, provide one or more enclosed private spaces where a qualifying patient may consume medical marijuana.”

Can you travel with marijuana in Missouri?

Medical marijuana patients can travel with their medicine in Missouri. However, it must be kept in a closed container and out of the driver’s reach.

Driving under the influence (DUI) of cannabis is illegal, with no exceptions for medical marijuana patients.

You also can’t travel with marijuana outside of Missouri. Doing so may result in federal felony charges for drug trafficking. You can be sent to 5 years in prison and pay $250,000 in fines if you’re caught with less than 5 kg of marijuana or fewer than 50 plants.

Is buying weed online an option in Missouri?

It depends on what kind of purchases you have in mind. If you want to order weed for delivery in Missouri, then you have to be aware of the weight limit to prevent legal trouble.

However, you can order your medicine online and pick it up later in one of the dispensaries that offer such services.

Is CBD oil from hemp legal in Missouri?

Yes. Hemp-derived CBD oil became legal in Missouri in 2018 when President Trump signed the amended Farm Bill.

The new law drew a thick line between hemp and marijuana, reclassifying the former as an agricultural commodity.

Hemp can be grown and sold for any use, from clothes, ropes, and paper, to construction materials, biofuel, food, and health supplements like CBD oil.

However, since the market is largely unregulated for hemp-derived supplements, I recommend buying CBD products from a reputable online store.

Buying Weed in Missouri: Bottom Line

Missouri is a great place to be if you’re a medical marijuana patient. You can choose from a wide selection of cannabis-based medicines and grow up to six plants at home. Some dispensaries also offer online ordering for pick-up.

Recreational marijuana users can now rejoice as this has been made legal through ballot initiatives. Residents can carry, use, and grow marijuana as long as they stay within the weight limits and are of legal age.

You can also try out delta-8 THC. It’s a psychoactive cannabinoid that’s also legal in Missouri, so you shouldn’t have problems finding it in your local store or online.

Just make sure to carefully check your delta-8 vendors to avoid scammers and contaminated products.
