Cannabis has quickly become a part of everyday life for many Missourians since legalization, offering both medical relief and recreational enjoyment. In Missouri—including right here in O’Fallon—adults can legally purchase cannabis for personal use, and patients can access it for health needs under the state’s medical marijuana program. If you’re new to cannabis or curious about what it’s all about, this guide will help you get started with confidence.

Understanding Cannabis: THC, CBD, and Other Cannabinoids

The cannabis plant contains dozens of natural compounds called cannabinoids. The two best-known are:

  • THC (Tetrahydrocannabinol): The compound responsible for the "high" feeling. It’s psychoactive and provides effects like euphoria, relaxation, or sedation depending on dose and strain.
  • CBD (Cannabidiol): Non-intoxicating and often used for stress, inflammation, and anxiety. It won’t get you high, but it may help you feel better.

There are also other minor cannabinoids like CBG, CBN, and THCV, which are gaining attention for their own unique effects.

Cannabis Strains: Sativa, Indica, and Hybrid

You’ll often hear cannabis described as:

  • Sativa: Energetic, uplifting, good for daytime use
  • Indica: Relaxing, body-heavy, ideal for nighttime or rest
  • Hybrid: A mix of both, designed to create balance

These terms are loose guidelines. Effects vary by person and depend heavily on the terpene profile—aromatic compounds that influence scent, flavor, and effect.

Medical vs. Recreational Cannabis in Missouri

Missouri offers both medical and recreational cannabis access:

  • Medical cannabis is available to patients with a qualifying condition and a valid Missouri medical marijuana card.
  • Recreational cannabis is legal for any adult 21+ and requires only a valid government-issued ID at purchase.

Key differences:

  • Medical patients can buy up to 6 ounces per month and pay lower taxes.
  • Recreational users can purchase and possess up to 3 ounces at a time.

Different Ways to Use Cannabis

There are many consumption methods, each offering a different experience:

1. Smoking or Vaping Flower

  • Fast-acting (2–5 minutes)
  • Lasts 1–3 hours
  • Classic method for many users

2. Edibles (Gummies, Chocolates, Beverages)

  • Slower onset (30–90 minutes)
  • Lasts 4–8 hours
  • Easy to overconsume if you’re not patient. Start low (2.5–5mg THC) and wait.

3. Tinctures and Sublinguals

  • Dropped under the tongue or added to drinks
  • Moderate onset time (15–45 minutes)
  • Easy to dose precisely

4. Topicals (Creams, Balms)

  • Applied to the skin
  • No psychoactive effects
  • Good for localized pain or inflammation

5. Concentrates

  • Highly potent extracts for experienced users
  • Used with vape pens or dab rigs
