This one confuses people because the marketing does NOT help. Let's clear it up.

What's in a "regular" THC cart

A dispensary delta-9 cart is usually THC distillate (sometimes live resin) with cannabis terpenes. Straightforward.

What's in a THCa cart

Here's the thing: THCa itself is a solid crystal at room temperature. You can't fill a cart with pure THCa, it would just be a tube of rocks. So "THCa carts" are usually one of these:

• Liquid diamonds - THCa diamonds melted down and blended with live resin or terpenes. This is the good stuff and it's what reputable vendors mean by a THCa cart.
  
• A blend - some THCa plus other hemp-derived cannabinoids (delta-8, HHC, etc.) to keep it liquid and cheap. Not necessarily bad, but you should know what you're buying.
  
• Mystery juice with THCa on the label - the COA tells the real story, if there is one.
  

Does a THCa cart get you high like a regular cart?

Yes. The heat from the coil decarbs THCa into THC as you puff, same principle as smoking flower. A real liquid diamond cart is functionally equivalent to a strong delta-9 cart.

How to tell what you're actually holding

The COA, always the COA. Look at the cannabinoid table:

• Mostly THCa with some minor cannabinoids and terps = liquid diamonds, legit
  
• A pile of delta-8 with a sprinkle of THCa = a delta-8 cart wearing a THCa costume
  
• No COA = put it down

One practical warning

THCa carts can crystallize back into solid form if they sit, especially in cold weather. If your cart looks like it has sugar or glass forming inside, that's actually a sign of high THCa content, not a defect. Warm it gently (pocket heat, not a lighter) and it'll flow again.
