How Long Does THCA Stay In Your System? Drug Test Timeline

A big question many people have about THCa flower is: will it show up on a drug test, and if so, for how long? The answer depends on several things, like how often you use it and the type of test being done. In this article, we’ll explain how THCa works in the body, how long it may stay around, and what you need to know about drug testing.

How THCa Works in the Body

THCa is the raw form of THC. On its own, THCa is not psychoactive, but once it’s heated (smoked, vaped, or cooked), it changes into THC.

Even raw THCa can show up as THC in your body once it’s processed, which is why drug tests can detect it.

How Long THCa May Stay in Your System

The exact time varies, but here are some general timelines:

• Urine Tests (most common) → THCa/THC can show up for 3–30 days, depending on how often you use it.
• Blood Tests → Usually detect THC for up to 24–48 hours after use. Heavy users may show longer.
• Saliva Tests → Can detect THC for 1–3 days.
• Hair Tests → May show THC for up to 90 days.

Factors That Affect Detection Time

• Frequency of Use: Daily or heavy users may test positive longer than someone who uses occasionally.
• Amount Taken: Higher doses usually stay in your system longer.
• Body Type: THC is stored in fat cells, so metabolism and body fat percentage can make a difference.
• Test Type: Some tests are more sensitive than others.

Things to Keep in Mind

• Even Legal Doesn’t Mean Test-Free: Even if THCa flower is legal in your state, it can still lead to a positive test.
• Raw THCa Counts: Consuming raw THCa (without heat) may still cause a positive result since the body can process it as THC.
• No Guaranteed Timeline: Everyone’s body is different, so it’s impossible to know an exact “safe” window for passing a test.

THCa can stay in your system for anywhere from a couple of days to several weeks, depending on how often you use it and the type of test. If you know you’ll be tested, the safest choice is to avoid use ahead of time.
