https://www.drugabuse.gov 很痛苦地发现，大麻对大脑的危害很难界定。原因是啥？

[春风吹]

The ability to draw definitive conclusions about marijuana’s long-term impact on the human brain from past studies is often limited by the fact that study participants use multiple substances, and there is often limited data about the participants’ health or mental functioning prior to the study. Over the next decade, the National Institutes of Health is funding the Adolescent Brain Cognitive Development (ABCD) study—a major longitudinal study that will track a large sample of young Americans from late childhood (before first use of drugs) to early adulthood. The study will use neuroimaging and other advanced tools to clarify precisely how and to what extent marijuana and other substances, alone and in combination, affect adolescent brain development.

看来，大麻还真不是你冒险的尽头，很可能只是开始啊。

大麻产业的背后是一个巨大的利益集团, 不断地通过各种媒体对公众洗脑并游说政府, 力促让其合法化. 目前看来已经得逞了.

合法化后, 吸多少克之内大麻可以开车 有法律规定了吗? 细思极恐啊.

好多种大麻发财？是不是最好买那种带moonroof的。光线好，大麻成熟期短，一年一车可以收割好多次。
