Your nephew's problem is a common problem seen in teens betweene 15 to 20 years. During this period, these boys explore and land up in addictions. You should take help from a good clinical psychologist
to resolve this problem. Choosing to train as an electrician will
not pose any problem. So, do not worry. Encourage and motivate him to busy himselv
es on pursuing his dreams. Follow the advice of your clinical psycologist.
Feel free to ask any additional queries.
Wish you and your nephew good health.
