It can affect brain development.

The most likely true statement about marijuana is that it can affect brain development.

To determine which statement is most likely true about marijuana, we need to evaluate each option.

1. "It can affect brain development."
This statement is a widely accepted scientific fact. The active compounds in marijuana, such as THC, can interfere with brain development, particularly in adolescents and young adults whose brains are still developing.

2. "It has no risk of addiction."
This statement is inaccurate. While marijuana addiction is generally considered to be less severe than addiction to substances like alcohol or opioids, it is still possible to develop a dependency or addiction to marijuana.

3. "It is harmless to most teens."
This statement is not entirely true. While some people may use marijuana without experiencing significant harm, it can have adverse effects, particularly on developing brains. The potential harm may vary depending on the individual, frequency of use, and dosage.

4. "It is legal for people over 18 years old."
Whether marijuana is legal for people over 18 years old depends on the jurisdiction. Laws regarding marijuana use and possession vary across countries, states, and even cities. Some regions have legalized marijuana for both medical and recreational use, while others may enforce strict regulations or prohibit it entirely.

Based on these considerations, the statement "It can affect brain development" is most likely true about marijuana, as it aligns with scientific research and understanding.
