How do I know if my vape is is a fake/laced?

To determine whether an e-cigarette product is counterfeit or illegally adulterated (i.e., "added with substances"), one can mainly rely on two aspects: the clues observed by oneself and the official testing channels.
Four-step self-check method (quickly identifying suspicious products)
The "observation, listening, questioning, and palpation" four-character formula summarized by the Chinese anti-drug departments is a practical self-check method:
Wang: Observe abnormal features
Packaging and appearance: Be vigilant of devices without brand logos and with strange shapes. If the packaging contains enticing words such as "Special E-liquid", "Special Experience", "High", or if the seller uses code words, the risk is extremely high.
Liquid characteristics: If the e-liquid is cloudy, stratified, or contains unknown suspended substances, it is a warning sign.
Wen: Identifying abnormal odors
The normal smell of an electronic cigarette (especially the tobacco flavor) is relatively simple. If you detect a pungent chemical solvent smell, an overly sweet aroma, or a mixed medicinal smell, you should be highly vigilant.
Question: Verification of sources and statements
Be vigilant against misleading propaganda: Be skeptical of statements such as "legitimate new trend", "non-addictive", "fuel for aircraft", etc.
Refuse to accept sources that are unclear: If the seller cannot provide formal production qualifications or ingredient descriptions, and merely uses reasons such as "recommended by friends" or "the same style as online celebrities", they should be firmly refused.
Cut: Be alert to your body's reactions and seek help.
If after taking the drug you experience symptoms such as dizziness, nausea, unsteady walking, confusion, uncontrollable laughter or emotional instability, it is very likely that you have consumed illegal substances.
Take immediate action: If you discover any suspicious products or experience adverse reactions, stop using them immediately, keep the evidence, and report to the police or seek medical attention promptly.
Official testing and verification (to obtain authoritative conclusion)
If you have doubts about the authenticity and safety of the product, seeking official testing is the only way to obtain an authoritative conclusion.
Identification basis: According to national regulations, counterfeit or substandard electronic cigarette products that infringe upon registered trademarks or are of poor quality must be identified by an electronic cigarette inspection and testing institution certified by the State Tobacco Monopoly Administrative Department of the State Council.
Test items: Professional testing institutions will conduct a comprehensive analysis of the actual nicotine content in the smoke liquid, the ratio of propylene glycol to glycerin, the presence of heavy metal residues, formaldehyde, benzene compounds, and whether any illegal and prohibited ingredients (such as synthetic cannabinoids) have been illegally added.
How to submit for testing: Generally, it is necessary to contact the local tobacco monopoly bureau or a third-party testing institution with relevant qualifications. You can make an inquiry first to understand the testing process and the required sample quantity.
⚠️ Special attention required: "Upgraded Electronic Cigarettes"
Currently, the ones with the highest risks on the market are the "upgraded electronic cigarettes" that disguise themselves as ordinary ones. They have been seized in multiple places. They may look ordinary, but the e-liquid often contains illegally added synthetic cannabinoids (such as the components in "Bird"), etomidate, fluanidine, etc., which are anesthetics or hallucinogens. Using them poses extremely great harm and is considered a form of drug use. Please stay away from them.
