Are E-Cigarettes Safe?
We have invested in professional teams and advanced equipment to strictly control product quality and provide users with high-quality and reliable harm reduction products.
Recent FDA research shows that e-cigarettes are generally a lower-risk alternative for adult smokers, but they are not risk-free. They release harmful chemicals and contain addictive nicotine.
If adult smokers can completely switch from cigarettes to e-cigarettes, they may reduce their exposure to many harmful chemicals in cigarettes and gain health benefits. However, it should be noted that long-term combined use of cigarettes and disposable E cigarettes may pose health risks comparable to, or even compound, those of smoking alone.

Traditional cigarettes produce over 7,000 chemicals when burned, at least 70 of which are carcinogens, such as polycyclic aromatic hydrocarbons (PAHs) and nitrosamines. They also contain tar, carbon monoxide, and heavy metals. Tar contains over 40 carcinogens, carbon monoxide reduces the blood's oxygen-carrying capacity, and heavy metal accumulation affects organ function and may cause cancer.
Disposable vapor cigarettes produce aerosols by heating liquids containing nicotine and flavorings. While the lack of combustion reduces the carcinogens produced by combustion, they are not completely harmless. Propylene glycol, glycerin, and flavorings in the liquids can produce toxic substances when heated, and can also release harmful substances such as aldehydes, ketones, and volatile compounds.

3. Conclusion
While progress has been made in current research on e-cigarette, there are still limitations. Due to the relatively short history of e-cigarette use, there is a lack of long-term, large-scale studies to fully assess their health impacts. However, existing research has clearly shown that e-cigarettes are not harmless; they contain nicotine and other addictive substances and still release harmful chemicals.
For adult smokers who have already been smoking, using disposable vapor cigarettes
that meet international standards can significantly reduce exposure to harmful substances and lower health risks, and thus can be regarded as a "harm reduction" tool. Relevant research is also continuing to advance to gain a deeper understanding of its advantages and disadvantages.

Battery Safety Guidelines
You may have seen reports about disposable E cigarettes battery explosions in the media. So what is the primary cause of e-cigarette battery explosions? It's simple: improper maintenance by users. For e-cigarette beginners, these tips may help prevent e-cigarette batteries or e-cigarettes from exploding.
Disposable e-cigarettes are equipped with non-replaceable lithium batteries and feature a sealed design. To use them safely, please note:
Do not use damaged charging equipment when charging; do not connect to a computer's USB port; avoid overcharging or fast charging.
Keep away from extreme temperature environments, and prevent impact or extrusion—this avoids battery damage that could lead to short circuits or liquid leakage.
Do not discard used devices randomly; they must be disposed of in compliance with regulations.
For e-cigarettes with replaceable batteries, please follow these rules:
Do not carry loose batteries in your pocket or bag. Contact between the battery and coins, other batteries, or other conductive items may cause a battery short circuit.
Never leave a charging battery unattended, and do not charge the battery near heat sources or flammable substances.
Do not overcharge the battery, as this will damage it. After the battery is fully charged, make sure not to leave it plugged into the power source.
Never store batteries in extreme temperatures, and avoid direct sunlight.
Turn off the vape battery when not in use.
Never use batteries that show signs of damage or have come into contact with liquids.

All ingredients are made from high-purity raw materials. PG and VG are of USP grade, flavors are food-grade, and nicotine is pharmaceutical-grade. We strictly adhere to international standards such as RoHS, CE. For markets requiring regulations like TPD and PMTA, we ensure our products fully comply with local regulatory requirements.
Product Ingredients
It has a wide range of applications, from food and pharmaceuticals to entertainment, so it is produced in large quantities. It adds almost no flavor by itself and can prevent packaged food from drying out. In many oral and topical medications, it is used as a stabilizer. In theatrical productions, PG is used to simulate smoke. PG is included in e-liquids because it mixes well with flavoring ingredients and produces smoke-like vapor when heated. Due to its slight irritancy, it also mimics the sensation of inhaling cigarette smoke.
Vegetable Glycerin (VG) has similar properties to PG. It is almost entirely derived from plants and widely used in the production of food additives and pharmaceuticals. It also imparts sweetness to food and helps keep food moist. VG is used in e-liquids for roughly the same reasons as PG. Since VG is thicker than PG, e-cigarette users opt for e-liquids with a higher VG content when they want to exhale thicker, more voluminous vapor.
Tobacco flavors themselves are combinations of different flavoring chemicals. Nearly all flavoring ingredients used in e-liquids are the same as or similar to those used in food and beverages. The food/beverage industry uses a wide variety of flavors, and the same is true for e-liquids used in vaping products. The most common categories include: fruits, desserts, candies, mints, beverages, tobacco, and savories/spices.
Since nearly all e-cigarette users are currently smoking or have switched to e-cigarettes to quit smoking and enjoy the benefits of nicotine, nicotine is a key ingredient in many e-cigarettes. A practical advantage of e-cigarette devices over traditional cigarettes is that they allow users to control their nicotine intake with considerable precision.

User Reviews
★★★★★
As a long-time smoker trying to switch to e-cigarettes, this disposable e-cigarette has completely exceeded my expectations! I chose the mint tobacco flavor—it has the rich taste of tobacco when inhaled, paired with the freshness of mint, no strange aftertastes at all. The smoke output is also very consistent, never fluctuating. I sincerely recommend it to anyone looking to switch to e-cigarettes.
★★★★☆
I bought the pod-based e-cigarette, and replacing the pod is super easy. Just align it with the port and press gently—it locks in securely, no loosening or leakage issues. I even accidentally dropped the e-cigarette on the floor once, and the pod didn't fall out. The sealing design is really well-done. These small details make it so user-friendly and hassle-free to use!
★★★★★
They have so many flavor options! Besides classic tobacco and mint, there are fruit flavors and cola flavor too. I tried the grape and apple flavors, and they're absolutely amazing—no cloying taste, just really smooth to inhale. Whether you prefer traditional tobacco tastes or want to try something new, you'll definitely find a flavor that suits you. It's truly fantastic!

★★★★★
I ordered custom-printed logos for disposable e-cigarettes for a company event. I was worried about the hassle of the process, but the customer service was incredibly professional. They proactively confirmed the logo's size and color, provided three draft designs, and only started production after confirmation. They also regularly updated the production progress and clarified delivery arrival times. Upon receiving the products, each logo was clearly printed without a flaw. Sanlei's custom service is professional and worry-free. I'll definitely choose them again for my next bulk purchase.

Can E-Cigarettes Explode?
E-cigarette explosions are relatively rare, but certain risks do exist. One potential cause of explosions is related to the lithium-ion batteries used in these devices. If handled improperly or exposed to extreme conditions—such as high temperatures or physical damage—the battery may malfunction, leading to an explosion or fire. Sanlei pods undergo strict quality control before being launched on the market, so you don't need to worry about Sanlei e-cigarettes exploding during normal use.
