Lawyers Appeal Brittney Griner's Russian Prison Sentence

A woman was found guilty of drug charges in Russia and sentenced to 9.5 years in prison. Her lawyers are appealing the sentence, arguing it is excessive compared to similar cases, which average five years. She has been in custody since February after being arrested for possessing vape cartridges with marijuana oil.

Since when has the individual been in custody?

What substance was found in the vape cartridges?
