Cannabis extract is sensitive to temperature. Stored in a hot environment — a glove compartment in summer, a pocket in direct sun, near a heater — the extract can change consistency, the battery degrades faster, and overall performance suffers.
Room temperature is ideal. Somewhere cool and out of direct sunlight is even better. The product on the shelf at a well-run dispensary is kept at a consistent temperature for a reason.
Cold temperatures make full-spectrum extracts thicker and slower-moving. A vape that was left in the cold may feel restricted or unresponsive when you first try to use it. Warming it in your hand for a minute or two usually fixes this — the extract loosens, the draw opens up, and the device performs normally.
If it remains completely unresponsive after warming up, that's less likely to be a temperature issue and more likely a hardware problem.
Debris in the mouthpiece is one of the most common but least obvious causes of a poor draw. A partially blocked airpath doesn't stop the device from firing, but it restricts vapour and makes the draw feel tight and unsatisfying. A quick visual check and a gentle clear of the mouthpiece is all it takes.
Don't use anything sharp inside the mouthpiece — you risk damaging the airpath or pushing debris further in.
Storing a disposable vape horizontally for long periods can cause the extract to migrate toward the mouthpiece or away from the coil, depending on which direction it's angled. Over time that can cause flooding (extract on the mouthpiece) or dry firing (coil heating with no oil in contact).
Keeping it upright — mouthpiece up — is a small thing that helps the device perform consistently through its full life.
