What key point about synthetic drugs is highlighted in the material?

The key point about synthetic drugs that is highlighted is that they often lack regulation. This lack of regulation is critical because it leads to several public health concerns. Synthetic drugs are often formulated to mimic the effects of existing controlled substances, but they may not be subject to the same safety and efficacy standards. This means consumers cannot be certain of what they are consuming, which can lead to dangerous side effects and unpredictable outcomes.

Without regulatory oversight, manufacturers can alter the chemical composition of these synthetic drugs to evade legal restrictions, making it difficult for law enforcement and health officials to track and manage their use. The absence of regulation also hampers research into their effects and potential risks, leaving users vulnerable. In contrast, other options suggest attributes that do not reflect the realities or the dangers associated with synthetic drugs.
