A vape headache often feels like a dull, throbbing, or pulsating pressure around the head, sometimes accompanied by nausea, fatigue, sensitivity to light/sound, or dizziness, stemming from nicotine's effects (blood vessel constriction, CNS stimulation) or dehydration, and can range from mild tension to severe migraines, especially with high doses or nicotine withdrawal.
Some types of headaches are more common with nicotine use, including: Cluster headaches: This severe, focused pain can last for 30 to 45 minutes at a time. You may get cluster headaches up to eight times a day for weeks or months.
200–500 puffs/day – Moderate use (so, weekends, stressful days, or those with less nicotine per puff). 500+ puffs/day – This tally may be considered on the high side, but it's not unheard of. It's actually quite common among vape enthusiasts using direct-to-lung (DTL) devices or very low nicotine strengths.
Short-term side effects of vaping include:
EVALI may cause the following symptoms:
The most popular illegal brands are IGET, HQD and Gunpod. These products generally have shoddy construction, are mislabelled (to get through Customs) and do not have safety warnings or an ingredient list. None meet Australian TGO 110 standards but they are still likely to be far safer than smoking.
Yes, lungs can begin to heal and show significant improvement after 7 years of vaping once you quit, with inflammation decreasing and lung function improving, but the extent of recovery depends on the damage; the sooner you stop, the better the chance for healing, though extensive, long-term damage might be permanent, emphasizing the need to quit for the best possible outcome and consulting a doctor for persistent issues.
Symptoms of nicotine poisoning include:

Days 1–5: Breaking Addiction
Expect to feel emotional irritability and anxiety, while physically, you may experience headaches or an increased appetite as you fend off strong cravings. Your body is starting to clear itself of nicotine.
There's no exact number, but roughly 10-15 vape puffs can equal one cigarette, though this varies greatly; it could be as few as 4 puffs with high-nicotine liquid or up to 50 puffs with weaker liquid, depending on puff duration, device power (pod vs. mod), and e-liquid strength (like 5% vs. 12mg/mL). A single cigarette delivers about 1-2 mg of nicotine, while a vape's nicotine delivery changes significantly with user style and device settings.
While vaping may be marketed as a safer alternative to smoking, it poses serious risks to indoor air quality and health, especially when done indoors. The chemicals released, the long-term contamination of surfaces, and the health risks to occupants all highlight why vaping indoors should be avoided at all costs.
Because vaping is far less harmful than smoking, your health could benefit from switching from smoking to vaping. And you will reduce your risk of getting cancer. Switching from cigarettes to e-cigarettes could also save you a lot of money.
Heavy vaping can be harmful to health, so it's important to practice moderation. Vapers should aim to keep their puff count within a safe range. Studies suggest that approximately 140 puffs per day are safe for most vapers. Puff counters can be useful tools for tracking vaping habits and staying within safe limits.
Adolescents are also at higher risk for vaping-related brain fog, attention deficits, and mood disorders. A study in college students found that students who vaped showed worse performance on cognitive tests [7]. This may be related to reduced blood flow to the brain and increased stress to brain cells.
Symptoms include vomiting, rapid heart rate, unsteadiness and increased salivation.

Symptoms of Vaping-Related Lung Damage
We know that vaping can damage your lungs and harm the brain, which is still developing and maturing into your late 20s. The long-term effects of vaping aren't known yet, but what we know right now isn't great. There's no such thing as safe vaping, even occasional vaping can be harmful to your health.
How to Do a Lung Detox
Brain damage: Nicotine can harm parts of the brain that control mood, learning, attention and impulse control. This can be especially problematic for young people, whose brains are still developing. Brain damage from nicotine and its neighboring chemicals can't be reversed and lasts a lifetime.
Do not use THC-containing e-cigarettes or vaping products. Avoid using informal sources, such as friends, family or online dealers to obtain a vaping device.
However, early research shows that vaping, even without nicotine, is not a completely safe alternative to cigarette smoking.
An IGET Bar vape's equivalent to cigarettes varies but can range from about 200 to over 400 cigarettes because of high nicotine content (often 50mg/ml) and many puffs (3500+), with calculations suggesting one bar might equal around 230 cigarettes for heavy users, though actual absorption depends on individual vaping habits.
