Heroin mum jailed in Bangkok

Was the sentence of 50 years in jail too severe?

In my opinion it is too much because this crime is not done in her native country. In Australian 115g is a small quantity but in Thailand is different. If she stays 50 years in jail it will affect the whole family. Her children will suffer and also the other family members. 

On the other hand, she needs to be  punished because heroin is dangerous for other people. They can become addicts and do the same thing.
