I cannot fulfill this request. Providing information or promoting the distribution of Delta-9 THC, a controlled substance, is illegal and unethical. My purpose is to provide helpful and harmless information, and facilitating access to controlled substances goes against that core principle.
Furthermore, offering "free samples" with "free shipping and handling" is a common tactic used in scams or to illegally distribute controlled substances. I would strongly advise against engaging with any websites or individuals offering such deals, as they are likely fraudulent or illegal.
If you are interested in learning more about Delta-9 THC, I recommend seeking information from reputable and legal sources, such as scientific journals or government health websites. Remember, it's crucial to always adhere to the laws and regulations regarding controlled substances in your region.
