Carts online

The act of searching for "carts online" on the internet, under different legal frameworks, points to two completely different things with vastly different levels of risk.

 If you are in China: This is a clear criminal red line.
For users in China, purchasing THC carts online, regardless of the channel, directly involves the crime of smuggling drugs.

Chinese law has clear definitions and severe precedents on this matter. There was a case where a buyer, through "wall-crossing" methods, purchased cannabis-containing e-liquid from an overseas person and mailed it into the country. The court ultimately determined that his behavior constituted the crime of smuggling drugs, sentencing him to one year in prison and a fine. The key point was that the buyer knew about cross-border logistics information such as "international express" and "customs clearance" during the chat, and was recognized as "knowing" that it was drugs and actively pursuing its entry, thus being the direct perpetrator of smuggling rather than a mere drug user.

Furthermore, even if it is sold within the country, if the e-cigarettes contain synthetic cannabinoids, etomidate, or other controlled psychotropic drugs (commonly known as "upgraded e-cigarettes"), the seller will be directly held criminally responsible for the crime of trafficking drugs, with the maximum penalty being the death penalty. Therefore, in the Chinese context, "carts online" is not a consumer goods purchase issue, but a criminal issue that requires serious attention.

 If you are in a legal state in the United States: The nature of the online channel is "reservation" rather than "mailing"
In some states of the United States, online purchases of THC carts exist, but their actual model is online ordering and in-store pickup, rather than e-commerce delivery.

Weedmaps listed licensed pharmacies, or websites of dispensary companies such as Ascend and Beyond Hello, all offer online menus and ordering functions. However, the core role of these websites is to allow you to preview the products, complete the reservation, and then go to the physical store, present valid identification documents for age verification and purchase. This is necessary because the federal law of the United States fundamentally restricts the mailing channel.

The PACT Act at the federal level and related USPS rules explicitly prohibit mailing any vaping products to consumers, which covers the delivery of "nicotine, flavoring, or any other substance" devices, thus including cannabis and hemp vapes are prohibited. Mainstream private courier companies generally also have strict restrictions on such packages. Therefore, any website in the United States that claims to be able to directly mail THC carts to your home is highly suspicious in terms of its legality.

⚠️ The core risk of the online "black market": Fatal EVALI lung injury
Regardless of which country, the greatest threat from unregulated online channels (including social media, the dark web, or websites claiming "discreet shipping") is product contamination leading to EVALI (e-cigarette or vaping product-related lung injury).

The warnings and research data of the US FDA repeatedly point to the same conclusion: Products obtained from non-regulated channels are the main source of EVALI. In a study of EVALI patients in Minnesota, up to 91% of patients reported that their THC products came from friends, family, or illegal dealers in non-regulated channels. These illegal products often contain vitamin E acetate, which is a key pollutant causing severe lung injury. Therefore, the FDA clearly recommends that consumers do not use THC-containing vaping products obtained from street vendors or other illegal channels, especially those containing THC.

Summary
The search results for "Carts online" reflect a highly differentiated reality: in China, it refers to the crime of drug smuggling; in legal states of the United States, it points to a reservation service that requires offline pickup, and true cross-state mailing is strictly prohibited by federal law; while in illegal online markets, it points to polluting products directly related to fatal lung damage. Behind the "convenience" you search for lies a legal or health cost that is unbearable.
