How Much Concentrate Can I Buy in California? Legal Daily Limits Explained
In California, adults 21 and older can purchase up to 8 grams of cannabis concentrate per day at licensed dispensaries. This limit applies to recreational purchases and is tracked through the state's track-and-trace system.
How Much Concentrate Can You Buy in California? The Legal Daily Limit
Under California law (Business and Professions Code section 26001), adults 21 and older can purchase up to 8 grams of concentrated cannabis per day at a licensed dispensary. This limit applies to all recreational purchases, regardless of how many stores you visit. The same rule applies to online orders and delivery services like ours at Garden of Eden (Delivery) in Hayward.
| Product Type | Daily Purchase Limit (Recreational) | Notes |
|---|---|---|
| Concentrates (wax, shatter, oil, dabs) | 8 grams | Includes all forms of concentrated cannabis, regardless of THC percentage. |
| Vape cartridges & disposables | 8 grams (total concentrate weight) | Measured by the weight of the oil inside, not the cartridge hardware. |
| Edibles (THC-infused) | 100 mg THC per package; up to 8 grams concentrate equivalent | Each edible package cannot exceed 100 mg THC. The 8-gram concentrate limit applies to the total THC content across all edibles. |
| Flower (bud) | 28.5 grams (1 ounce) | Separate limit from concentrates. You can buy both 8g concentrate and 28.5g flower in one day. |
| Tinctures & topicals | 8 grams concentrate equivalent | Measured by THC content; if the product is non-intoxicating (e.g., CBD-only), it may not count. |
These limits are set by the California Department of Cannabis Control (DCC) and enforced at the point of sale. If you try to purchase more than 8 grams of concentrate in a single transaction, the system will block the sale. For medical patients with a valid Medical Marijuana Identification Card (MMIC), higher limits may apply—see the section below.
What Counts as Concentrate? Understanding the 8-Gram Limit
Not all cannabis products are created equal under the law. The 8-gram daily limit applies specifically to concentrated cannabis, which the state defines as any product that has been processed to increase the concentration of cannabinoids. Here's how common products break down:
| Product | Counts as Concentrate? | How It's Measured |
|---|---|---|
| Wax, shatter, budder, crumble | Yes | By weight of the concentrate itself (e.g., 1 gram of wax = 1 gram toward the 8g limit). |
| Vape cartridges & disposables | Yes | By the weight of the cannabis oil inside. A 1g cart counts as 1 gram of concentrate. |
| Edibles (gummies, chocolates, drinks) | Yes | By total THC content. 100 mg of THC is roughly equivalent to 1 gram of concentrate (varies by potency). |
| Tinctures & sublingual oils | Yes | By THC content; a 500 mg THC tincture counts as approximately 0.5 grams of concentrate. |
| Topicals (creams, balms) | Usually no (if non-intoxicating) | If THC content is negligible, it may not count. Check with your budtender. |
| Flower (raw bud) | No | Separate limit of 28.5 grams per day. |
So if you buy a 1-gram vape cartridge, a 500 mg THC tincture, and 3.5 grams of wax in one day, that totals about 5.5 grams of concentrate—well within the 8-gram limit. But if you add a 1000 mg edible (which counts as roughly 10 grams of concentrate), you'd exceed the limit. That's why 1000 mg edibles are not legal for recreational sale in California; the maximum per package is 100 mg THC.
Medical vs. Recreational: Does a Medical Card Let You Buy More Concentrate?
Yes, holding a valid Medical Marijuana Identification Card (MMIC) can allow you to purchase larger amounts of concentrate. While recreational users are capped at 8 grams per day, medical patients may be able to buy up to 8 ounces (roughly 227 grams) of concentrate in a single day—but this varies by dispensary and requires a doctor's recommendation. Here's a comparison:
| Factor | Recreational (21+) | Medical (with MMIC) |
|---|---|---|
| Daily concentrate limit | 8 grams | Up to 8 ounces (varies by recommendation) |
| Purchase limit per transaction | 8 grams | Higher, based on doctor's recommendation |
| Tax rate | Standard (15–25% depending on locality) | Lower (medical cannabis is exempt from some taxes) |
| Age requirement | 21+ | 18+ (with valid ID and MMIC) |
| How to get a card | Not applicable | Consult a licensed physician; register with the county for an MMIC |
If you have a medical need for higher doses, a medical card can be a practical way to legally access more concentrate. However, not all dispensaries honor out-of-state medical cards, and the specific limit depends on your doctor's recommendation. Always check with your local dispensary—like Garden of Eden (Delivery) in Hayward—about their medical purchase policies.
What Are the Penalties for Exceeding the Concentrate Limit?
Possessing more than the legal limit of concentrate can result in criminal penalties under California law. Here's a breakdown of what's at stake:
| Amount Over Limit | Possible Penalty | Notes |
|---|---|---|
| Up to 8 grams over (total 8–16g) | Infraction (similar to a traffic ticket) | Fine up to $100 for first offense. |
| 8–28.5 grams over (total 16–36.5g) | Misdemeanor | Up to 6 months in county jail and/or $500 fine. |
| More than 28.5 grams over (total 36.5g+) | Misdemeanor | Up to 6 months in jail and/or $500 fine; potential for felony charges if intent to sell is suspected. |
These penalties apply to possession, not just purchase. If you're caught with more than 8 grams of concentrate in public without a medical card, you could face legal consequences. The safest approach is to stay within the daily purchase limit and store your products securely at home. If you have a medical card, carry it with your products to prove lawful possession.

Do Dispensaries Track How Much Concentrate You Buy?
Yes, every licensed dispensary in California—including Garden of Eden (Delivery)—uses a state-mandated track-and-trace system called Metrc. This system records every purchase you make, including the product type, weight, and date. When you try to buy more than 8 grams of concentrate in a single day, the system automatically blocks the transaction at the register.
This tracking applies across all dispensaries you visit, not just one store. So if you buy 5 grams of wax at one shop and then try to buy 4 grams at another, the second transaction will be denied because your total for the day would exceed 8 grams. The system resets at midnight each day, so you can start fresh the next day.
For medical patients with a valid MMIC, the system allows higher limits based on your doctor's recommendation. But for recreational users, the 8-gram cap is strictly enforced. This ensures compliance with California's cannabis laws and helps prevent diversion to the black market.
