' G$ A5 o; v. r我问的不是百分比,而是你说的大麻导致精神疾病的证据,某一两个人的推测不能算数,因为google很容易找 ...

' i9 i0 e y$ L8 B: F4 @. r最后一次回答你。 when a doctor speaks to public in an interview,, she has to support her speach with her clinical or research evidence. They get peer critics. 然后你说一两个人的推测不算数。 I told you my opinion came from my work experience and the experts that I worked with. 你还可以说一两个人的推测不算数。 use your common sense. Why people love cannabis so much they develop addiction? It makes people feel high,or extremely relaxed, or whatever. Why? 大脑的功能依赖于一种很复杂的化学因素叫 neurotransmitters that act as carriers of information between cells called neurons. Tetrahydrocannabinol (THC), 也就是大麻的主要成分 会影响这个信号的传输功能。 0 X, M4 p/ ~' q
# Y$ |' T' d3 x- [4 ?9 @& L* j- s WTHC specifically interacts with brain proteins named cannabinoid receptors that are highly expressed in the brain. A higher density of these proteins exists in brain areas that are critical for learning, memory, pain perception, and reward processing. In fact, scientists think the activation of cannabinoid receptors in the brain’s reward pathways may underlie marijuana’s likelihood for abuse。 大麻这种物质会影响大脑中主管学习,记忆,疼痛的区域, 你觉得对青少年来说,是好事? 大麻会造成 short term and long term memory 的损害, 记忆力对学习的重要性不需要重复。8 l) u.

Despite the promise of medicinal cannabinoid drugs, concerns remain regarding the effects of marijuana on the developing brain. Marijuana abuse during adolescence may produce enduring changes in brain function, particularly in individuals at a greater risk for developing psychiatric disorders. Scientific research suggests that repeated marijuana use during adolescence (at least four joints per week) can increase the risk for psychosis, decrease adulthood IQ, and lead to changes in the brain that increase vulnerability to more dangerous illicit drugs. 以上信息来自http://www.brainfacts.org/about-neuroscience/ask-an-expert/articles/2013/how-does-marijuana-affect-brain-function/4 f+ ^7 @9 v7 I!

$ V0 l! `9 K: m& j' w4 H“ 无论大麻合不合法,它都在被广泛吸食,即便你能在这里压倒对方,你还能一天二十四小时跟着你小孩?合法化又不是鼓励孩子吸食,不会比烟酒的限制松的”1 _% Z' ^# v% d; R1 E
再说一次, 这不是一个单选题, 这是一个已经有了糟糕的, 还要来个糟糕的问题。 烟酒已经合法化无能为力。 大麻还可以至少努力一下。
" O/ i! k5 P( H& F5 x# m( g0 b' ?合法化的确不是鼓励吸食, 但是它传递了一个信息, 那就是很多人会认为它是无害的, 或者轻微的有害。 比如你自己。你之前了解大麻对神经系统的作用吗。 6 p& z9 Y* q0 |2 X
