The pick
Medical cannabis costs less and allows larger purchases than recreational cannabis for buyers with a qualifying condition. Colorado medical patients can buy 2 ounces of flower per transaction. Colorado recreational customers can buy 1 ounce. Illinois medical patients pay 1% state sales tax on cannabis. Illinois recreational customers pay 10% to 25% in state tax, plus local tax. A medical card runs $25 to $200 and needs a doctor visit. Regular buyers can recover that cost in tax savings within a few months.
Option 1: Medical cannabis
- Age: 18 in most states. Patients under 18 need a caregiver.
- Access: Physician certification plus a state card or registry entry.
- Tax: 0% to 1% state sales tax in several states. No state excise tax in some.
- Limits: Colorado 2 ounces per transaction. Illinois 2.5 ounces per 14 days.
- Products: High-CBD flower, tinctures, capsules, topicals, and 1:1 ratio products. Some states require a pharmacist on site.
Option 2: Recreational cannabis
- Age: 21.
- Access: Government ID. No doctor visit. No card.
- Tax: State excise tax plus state and local sales tax. Illinois tiers run 10% to 25% by THC content.
- Limits: Colorado 1 ounce per transaction. Illinois 30 grams of flower per purchase.
- Products: Edibles capped at 10 mg THC per serving and 100 mg per package in many states.
Option 3: Hemp-derived CBD
Hemp with 0.3% THC or less falls under the 2018 Farm Bill. Buyers need no card, no doctor note, and no state registry. Sellers ship across state lines. Batch lab reports list CBD and THC percentages. This route fits buyers who want CBD without a THC high and without a program fee.
State programs
About 40 states run a medical cannabis program. Half of the states allow adult-use sales. Rules on age, tax, purchase limits, and product types come from state law, not federal law.
difference between medical and recreational cannabis
Federal status
Cannabis sits in Schedule I of the Controlled Substances Act. Federal agencies do not recognize state medical cards. The FDA has approved one cannabis-derived prescription drug, Epidiolex, for two rare seizure disorders. The FDA has not approved CBD as a food ingredient or dietary supplement.
