Practicing drink safety is essential to protect yourself at parties, bars, clubs, and other social events. Physical barriers such as drink covers can make it difficult for someone to discreetly place a drug or other harmful substance into your beverage. However, no cover can eliminate the risk entirely. Whenever possible, watch your drink being prepared, keep it with you, avoid sharing beverages, and do not continue drinking anything that was left unattended or suddenly tastes, smells, or looks unusual.
If you suspect that your drink may have been tampered with, drink-testing strips, cards, or kits can screen a small sample for certain substances such as GHB or ketamine. These products may provide useful information, but they differ in which drugs they detect and may produce inaccurate results with certain beverages. A negative result does not prove that a drink is safe because the test may not detect every possible substance or concentration. If you are uncertain about a drink, the safest option is to stop drinking it. If you or someone else experiences sudden confusion, unusual drowsiness, difficulty walking, memory loss, vomiting, or other unexpected symptoms, stay with a trusted person and seek emergency medical assistance.
Can and bottle covers are compact barriers designed specifically for beverages served in aluminum cans or narrow-necked bottles. Unlike stretchable cup covers, which may fit awkwardly over these containers, can caps and bottle stoppers attach directly over the drinking opening. Can covers typically snap or stretch over the top of a standard or slim can and include a smaller opening for drinking. Bottle covers or stoppers fit into or over the mouth of a glass bottle and may include a straw opening or removable closure, while some models can be resealed between sips.
When choosing a drink cover, consider whether you prefer a reusable or disposable design, how securely it fits different cups or glasses, and whether it is compact enough to carry consistently. Also look for practical features such as a straw opening, spill resistance, and ease of cleaning. When comparing drink-testing products, review which substances each test detects, how quickly it produces results, its expiration date, and the instructions and limitations provided by the manufacturer. Because products vary considerably in price and scope, consider whether you want an affordable test for one or two commonly used substances or a broader screening kit that detects multiple drugs. Cost per test and portability also matter if you plan to carry or use the product regularly.

NightCap is an excellent option for someone who wants a reusable drink cover that is easy to carry. The scrunchie version is especially convenient because it doubles as a wearable accessory, while the keychain version is a practical alternative for anyone who prefers to attach the cover to a bag or set of keys. Its stretchy material fits most standard cups and glasses, and the straw opening allows you to continue drinking without repeatedly removing the barrier. However, NightCap should be treated as an added barrier rather than a guarantee against drink tampering, so watch your drink, do not leave it unattended, and stop drinking if you notice anything unusual.

- Does not test for GHB or every possible substance that could be used to spike a drink
- Requires only 3 drops of a beverage to perform a test
- Produces results through a series of colored lines, generally within 3-5 minutes

Knope stands out for its ability to screen for several benzodiazepines and ketamine, making it a useful complement to products focused primarily on GHB. To use the test, place 3 drops of the beverage onto the device, wait the instructed amount of time, and interpret the colored lines using the enclosed guide. Its compact, single-use format makes it convenient for nights out, parties, trips, and festivals. However, the test is intended for specific beverage types and does not detect every possible drink-spiking substance, including GHB. If the result is positive, unclear, or invalid, or if you remain suspicious despite a negative result, stop drinking the beverage, move to a safe location, notify someone you trust, and seek help if necessary.

DrinkStrips Nail Stickers
- Wearable, single-use nail stickers designed to screen a beverage for GHB
- Applied to the nails before going out, keeping the test immediately accessible
- Requires only one drop of a beverage on the sticker’s detection area
- Produces a color-based result in 10-15 seconds
- A change from fully yellow to partially green indicates possible GHB contamination
- Works with alcoholic and non-alcoholic beverages
- Compact and discreet, resembling decorative nail art
- Each resealable pouch contains 10 stickers
- Each sticker can only be used once
- Brand also offers standard strips for broader screening
DrinkStrips Nail Stickers are an innovative choice for someone who wants to keep a drink test readily available without carrying or opening a separate packet. After applying the stickers before going out, the wearer can place one drop of a beverage on a sticker and check for color change within seconds. Their subtle appearance makes testing more discreet at a bar, party, concert, or festival. However, the nail stickers test only for GHB, so the brand’s standard strips are the better option for broader screening that also includes ketamine, scopolamine, and cocaine. Whichever format you choose, treat the result as a screening tool rather than proof that a drink is safe. Stop drinking anything that seems suspicious, even if the test is negative.
