Assuming my prefrontal cortex was equally immature at 17,I was never in possession of a large quantity...or ANY quantity...or women's jewelry at that age.And that's just one of the curious differences that existed between NoLimitsNigga and I at the age of 17.
Marijuana use inhibits defelopment of the prefrontal cortex. It's generally fully developed by age 20-22, so the effect isn't significant in people who become users later in life, but produces "arrested development" in people who start using it before development is complete.
Trayvon had the physical body of a 17 year old athlete, and quite possibly the reasoning and cognitive abilities of someone normally much younger. He was able to physically inflict considerable damage to another person (quite possibly lethal) and would have all the aggressive tendencies that come with the high testosterone levels normally present in 17 year old adolescents, but hadn't developed the ability to understand and predict the potential consequences of his own actions.
