How to Buy Cannabis in California: A Farmacy Buying Guide

Welcome to the Farmacy cannabis buying guide! To buy cannabis in California, you need to be 21+ with a valid physical government-issued photo ID or passport, or 18+ with valid medical documentation.

Once you’re through the door, the two decisions that matter most are format (how fast it comes on and how long it stays) and effect (what you actually want to feel), not the THC percentage on the front of the package.

Here’s how to read a label, match a product to what you’re after, and get the most out of a conversation with your budtender.

How Do You Read a Cannabis Label?

Every legal cannabis product sold in California comes with a certificate of analysis (third-party lab results), and the important numbers are printed right on the package. Read them in this order:

1. THC % (flower and concentrates) or THC mg (edibles, tinctures, beverages). Percentage tells you strength per gram. Milligrams tell you strength per dose. For anything you swallow, only the milligrams matter.
2. CBD content, or the CBD: THC ratio. CBD softens how intense THC feels. A 1:1 product is a meaningfully different experience from a THC-only one at the same THC number.
3. Terpene profile. The aromatic compounds that give cannabis its character. This is the most useful line on the label, and the one almost nobody reads.
4. Total cannabinoids. This includes minor cannabinoids like CBG and CBN, which do contribute to the overall experience.
5. Harvest or packaged date. Flower degrades. Fresher is better, and if a package date is more than a year old, ask about it.
6. The state warning and license number. Their presence is how you know you’re buying tested, legal product.

The most common mistake: shopping on THC percentage alone. Potency is a spec, not a quality measure. A 21% flower with a rich terpene profile routinely beats a 34% flower with a flat one.

What Do Terpenes Actually Do?

Terpenes are the aromatic oils in cannabis that give it its different aromas and tastes, and they’re a big part of why two products with identical THC numbers can feel like completely different plants. Here are the ones you’ll hear about most:

These are tendencies, not guarantees. Everyone responds a little differently, and the full cannabinoid-plus-terpene combination matters far more than any single compound on its own. If you want to go deeper, our Journal covers each of them: the terpene guide introduction, myrcene, pinene and caryophyllene, limonene and terpinolene, and ocimene, linalool and bisabolol.

Which Product Type Should You Buy?

Start with format, not effect. How fast something comes on and how long it lasts will rule most of the menu in or out before you even get to what you want to feel.

New to this? Start with a low-dose edible, 2.5 to 5mg THC, or a small amount of flower, and wait out the full onset window before you take any more. Nearly every rough first experience is an edible taken again too soon.

There’s more depth in our Journal: the ultimate cannabis flower guide, the guide to pre-rolls, the definitive cannabis concentrates guide, using edibles for the first time, an intro to cannabis vaping, the complete guide to cannabis tinctures, topical vs. transdermal, and the 3 best cannabis beverages.

How Do You Match a Product to What You Want to Feel?

Start from the outcome and work backward to format and profile.

• For sleep. Look for myrcene- and linalool-forward products, and ask about CBN, a minor cannabinoid associated with sedation. Edibles and tinctures tend to suit sleep better than inhaled products, simply because the duration covers the night instead of fading in an hour. Our Journal goes further on cannabis and sleep.
• For focus. Lower THC, pinene- or terpinolene-forward, and inhaled rather than eaten so you keep control of the dose and can stop when you want. High-THC products work against focus for most people.
• For social settings. Limonene-forward, low to moderate dose, fast onset and shorter duration. Beverages and low-dose edibles are built for this. A heavy concentrate is not.
• For physical discomfort. Caryophyllene-forward products and higher CBD ratios, plus topicals for anything localized. Topicals are generally non-intoxicating, which makes them a daytime option.
• For creative work. Moderate dose, terpene-forward rather than potency-forward. We’ve written about cannabis and art if that’s your thing.
• Two rules that apply to all of the above: start low and go slow, and change one variable at a time. If you switch product, dose, and format all at once, you won’t learn anything about what actually worked.

What Should You Ask Your Budtender?

Ten questions that get you a genuinely useful recommendation.

1. “I want to feel [X] — what should I look at?” Lead with the outcome, not a product name.
2. “What’s the terpene profile on this, and what does that mean for how it feels?”
3. “What’s a starting dose for someone with my tolerance?” Be honest about how often you consume; there’s no wrong answer.
4. “How long until I feel it, and how long does it last?”
5. “What’s the CBD: THC ratio, and would more CBD help here?”
6. “Is there something comparable one price tier down?”
7. “When was this harvested or packaged?”
8. “Who grew this and where?”
9. “What are your team’s current picks in this category?”
10. “What would you not recommend for what I’ve described?” The most underrated question in the shop, and a good budtender will answer it straight.

Our budtenders build every recommendation from the effect you want, the format you prefer, and your tolerance, working inside a menu we’ve already narrowed down.

What Does a Quality California Dispensary Look Like?

Six things worth checking, wherever you shop:

• A visible state license. Every legal California retailer displays its C10 license number. Ours are in the site footer.
• Lab-tested product with accessible COAs. Staff should be able to pull up results for anything on the shelf.
• A curated menu, not an unfiltered catalog. Curation means things got turned down. We’re a family of retail stores offering premium, curated adult-use and medical cannabis.
• Local sourcing. Shorter supply chains mean fresher flower. We make every effort to source our products from local growers at all of our locations. More on where we source and why on our About the Farmacy page.
• Staff who ask before they recommend. If nobody asks about your tolerance or what you want to feel, you’re being sold to, not advised.
• Education that exists outside the sales conversation. Our free FOTF Lecture Series runs small, in-depth cannabis education sessions led by cannabis experts. Details on our Friends of the Farm page.

Where to Buy: Our California Dispensaries

We’re part of the Glass House Group family, alongside NHC and The Pottery. We’re genuinely rooted in the neighborhoods our stores are in, from Berkeley down to Santa Barbara County and Santa Ana, sourcing from local growers wherever we can and hiring locally.

How old do you have to be to buy cannabis in California?

21+ for adult-use, with a valid physical government-issued photo ID or passport. Medical patients can purchase at 18+ with valid state medical documentation.

Do you need a medical card to buy cannabis in California?

No. Adults 21+ can buy recreational cannabis with a valid photo ID. A medical card only matters for medical-patient purchase limits and for buyers aged 18 to 20.

Does a higher THC percentage mean better cannabis?

No. THC percentage measures potency, not quality or effect. Terpene profile, cannabinoid ratio, and cure quality shape the experience; a 21% flower with a strong terpene profile often beats a 34% flower with a flat one.

How long do edibles take to kick in?

Anywhere from 30 minutes to 2 hours, with effects lasting 4 to 8 hours. That gap is exactly why edibles are the easiest product to overdo: wait out the full window before taking more.

What’s a good starting dose for a first-time cannabis user?

2.5 to 5mg THC for an edible, or a small amount of inhaled flower where you control the dose and feel it within minutes. Wait the full onset window before you increase.

Is there a limit on how much cannabis you can buy?

Yes. Adults 21 and older can buy up to 28.5 grams of cannabis flower or 8 grams of concentrate per day. Edibles are capped at 10mg THC per serving and 100mg per package. Medical patients 18+ with valid documentation may purchase larger quantities, determined by their doctor’s advice.

What ID do you accept?

A valid physical government-issued photo ID or passport. Expired driver’s licenses accompanied by temporary renewals are no longer accepted.
