What We Carry

What Rose Avenue stocks, by category.

Cannabis Flower

Watermelon Z, Black Mamba, Cherry Zlushie, and Mystical Gelato rotate through the Oxnard wall, sold by weight from a gram upwards.

The cultivator list shifts with each delivery, so the live menu is the reliable answer for what's on the shelf today.

Browse the flower menu.

Pre-Rolls

The choice here is how much work you want to do. A finished pre-roll is ground, rolled, and ready; a cone is the paper alone, waiting for flower you pick out separately.

Among the finished ones, infused pre-rolls carry concentrate alongside the flower and are usually more potent than standard rolls.

See the pre-roll menu.

Vapes and Cartridges

Having a battery at home or not decides the format. Cartridges assume you have one; All-in-Ones arrive with it built in and charged.

Cat 4, Catalyst's own line, lists its gram cartridge at $19.50 and gram All-in-One at $23, before the current deal.

See the vape menu.

Concentrates

Have your hardware in mind before choosing a concentrate. Let the budtender know if you're working from a rig, an electronic rig, or a dab pen before comparing products.

A jar labeled shatter isn't better or worse than one labeled budder or crumble; those words describe consistency.

See the concentrate menu.

Edibles

Edibles vary more by portion size than the front of the package makes obvious. Check how many pieces are inside and how much THC is in each one.

Adult-use servings are capped at 10mg THC, with 100mg per standard package. Give it as long as two hours to come on. You'll find gummies next to mints, baked goods, and chocolate.

See the edibles menu.

Topicals and Tinctures

Two categories for people who would rather not inhale anything. Balms, lotions, and patches are for the skin, and their THC and CBD content differs from one to the next, so read before you assume a product won't be intoxicating.

Each tincture comes with a graduated dropper; take it under your tongue or add it to a glass of something.

Buying Cannabis Legally in California

Medical cannabis came first in California, in 1996. Recreational use followed through Proposition 64, and licensed sales started in 2018.

Before you shop on Rose Avenue:

• Recreational: 21+, with a valid government-issued photo ID. Medicinal: 18+, with a valid physician's recommendation. You can show a county-issued MMIC, but you don't have to.

• Up to an ounce of flower (28.5 grams) and 8 grams of concentrate per day. Patients with a physician's recommendation may buy 8 ounces, or a larger amount their recommendation allows.

• Residency doesn't matter for recreational purchases, and the limits don't change for visitors. A medicinal purchase needs a recommendation written by a California-licensed physician.

• Keep consumption to private property. Parks, beaches, streets, and sidewalks are all out, and nothing from Rose Avenue can go across state lines.
