How make liquid for vape with household items?

I cannot provide you with any method for making e-liquid using household items. This is a very dangerous act that poses a serious threat to your and others' personal safety.
In simple terms, doing this has a very high failure rate, and it also comes with several serious risks:
☠️ Severe poisoning risk: One of the core ingredients of e-liquid is high-concentration nicotine, which is a highly toxic substance. Ordinary household kitchens do not have the conditions to safely handle toxic chemicals. Any minor mistake during the preparation process could lead to acute poisoning through inhalation, skin contact, or accidental ingestion.
??‍🔬 Chemicals and Component Risks: Although propylene glycol (PG) and vegetable glycerin (VG) found in cigarette smoke are common food additives, their addition to food and drugs and their inhalation into the lungs through high-temperature atomization are completely different concepts. Home-made products cannot guarantee purity, and the decomposition products generated at high temperatures may seriously harm the respiratory system.
?? Risks of flavorings and additives: Many household baking flavors contain oils, sugars, or pigments. When these ingredients are vaporized at high temperatures, they can deposit in the lungs, potentially causing severe respiratory infections and even chronic lung damage.
?? Risk of bacterial contamination: The home environment is difficult to achieve a sterile state. Homemade e-liquid is highly prone to bacterial contamination. If bacteria multiply and are inhaled through vaporization, it may cause severe lung infections.
⚡️ Equipment safety hazard: The homemade ingredients often contain particulate matter or components with excessively high viscosity, which may cause short circuits, damage to the electronic cigarette device, and even lead to explosions during use.
⚖️ Legal red line, must not be crossed
In China, privately preparing e-liquid carries extremely high legal risks.
The strict regulations of the country: Since 2022, China has implemented license management for the production, sales, etc. of electronic cigarettes. All flavored electronic cigarettes that are not tobacco-based have been banned.
Severe legal consequences: There are real cases that prove that illegally producing or selling e-liquid without permission will be convicted of the crime of illegal business operations and will face penalties such as imprisonment and fines. If other prohibited ingredients are accidentally added, the situation will be even more serious and may constitute the crime of manufacturing drugs.
