What age should you give medical marijuana to a child

This is a tough question. I wouldn't recommend anyone taking medical marijuana if it is still illegal where you live, it is still a schedule 1 substance where I reside, but I do not think it should be. It can be useful to people with a vast variety of ailments, from cancer to work stress to seizures. Some forms of cannabis have shown potentially harmful to children under the age of 13, it changes the way the brain develops, in contrast; even caffeine at a young age can do this. But there are still ways for young children of any age to benefit, such as with the case of a young girl who suffered from extreme epilepsy, a derivative of cannabis oil given daily reduced her seizures from over 1000 times a day to less than ten times a day. In the end more research needs to be done into the effects of marijuana. Just like any other substance it is safest used by healthy adults only but children can use it in clinical settings. This does not apply to smoking it for recreational purposes though, "should give to a child" never exists. It is an enjoyment to adults and a medicine for others and should be treated as such.
