THC Vape Potency Limits in California: What You Need to Know
California's THC vape potency limit is 1 gram of THC per cartridge, not a percentage cap. This applies to all inhalable cannabis products, including vapes. THCa is also counted toward this limit. At Garden of Eden Hayward, we carry only compliant products.
California's THC Potency Cap for Vape Cartridges
California's THC vape potency limit is set by the Department of Cannabis Control (DCC) under Assembly Bill 1594. The rule: each vape cartridge or inhalable product cannot contain more than 1 gram (1,000 mg) of THC. This is a total weight limit, not a percentage cap. So a 1-gram cartridge can be up to 100% THC, but a 2-gram cartridge can only be 50% THC.
| Product Type | THC Limit | Example |
|---|---|---|
| Vape cartridge (1g) | 1 gram THC max | Full gram cart can be high potency |
| Vape cartridge (0.5g) | 0.5 gram THC max | Half-gram cart can be very potent |
| Disposable vape (1g) | 1 gram THC max | Disposable with 1g oil |
| Disposable vape (2g) | 1 gram THC max | 2g disposable must be diluted |
| THCa isolate vape | 1 gram total THC (including THCa) | THCa counts toward limit |
This limit applies to all inhalable cannabis products sold in licensed dispensaries across California, including Hayward, San Leandro, and Oakland. Always check the label for total THC content.
THCa Restrictions in California Vape Products
THCa is the non-psychoactive precursor to THC. When heated, it converts to THC. California counts THCa toward the 1-gram THC limit for vapes. So a cartridge with 500 mg THCa and 500 mg THC is at the max.
| Component | How It's Counted | Example |
|---|---|---|
| THC | Counts directly toward limit | 800 mg THC = 800 mg toward limit |
| THCa | Counts as THC (potential THC) | 200 mg THCa = 200 mg toward limit |
| Total THC | THC + THCa (and other precursors) | Must be ≤ 1,000 mg per cartridge |
When shopping, look for "total THC" on the label. This includes THCa. At Garden of Eden Hayward, our staff can help you read labels and find a vape that fits your needs while staying within legal limits.
