What Determines How Long a THC Vape Lasts
Several factors influence how long your 1g vape cart will last:
-
Puff Size & Duration: Short, light puffs consume less oil than long draws.
-
Frequency of Use: Casual users might take 20–30 puffs per day, while frequent users can double that.
-
Voltage & Temperature: Higher heat settings vaporize more oil per puff.
-
THC Concentration: Stronger carts require fewer hits for the same effect.
Average Puff Count and Duration
A standard 1-gram THC cartridge contains about 300–350 puffs.
-
Light user: 1–3 puffs per session → lasts 7–14 days
-
Moderate user: 5–10 puffs per day → lasts 3–7 days
-
Heavy user: 15+ puffs daily → lasts 1–3 days
| Usage Type | Avg. Puffs/Day | Approx. Duration |
|---|---|---|
| Light | 20–30 | 1–2 weeks |
| Moderate | 50–70 | 3–7 days |
| Heavy | 100+ | 1–3 days |
Tips to Make Your Cartridge Last Longer
-
Use lower voltage settings to preserve oil and terpenes.
-
Store upright in a cool, dry place to prevent leaks.
-
Take shorter, steady draws instead of long pulls.
-
Avoid chain-vaping, which overheats the oil and wastes THC.
Comparing Vape Longevity to Other Forms
| Product Type | Typical Duration | Notes |
|---|---|---|
| 1g Vape Cart | 3–10 days | Discreet, portable, fast onset |
| Edibles (100mg pack) | 2–4 sessions | Stronger, slower onset |
| Flower (3.5g) | 5–7 sessions | Classic form, less potent per hit |
Final Takeaway
A 1g THC cartridge’s lifespan depends on how often and how deeply you puff. Most users finish a 1g cart in about a week, but usage habits and potency make all the difference.
FAQs About THC Vape Cartridge Longevity
Do THC vape carts expire?
Yes. Most have a shelf life of 6–12 months. Over time, THC may degrade and terpenes lose flavour.
How can I tell when my vape cartridge is empty?
When vapour production drops and the oil turns dark or tastes burnt, it’s nearly done.
Can a THC vape get weaker over time?
Yes. Heat exposure and air oxidation can lower potency and flavour quality.
Does temperature affect how long it lasts?
Absolutely. Lower heat = slower oil use and better taste. High heat burns oil faster.
