Food and Drink

Carmine

Q: I had bought strawberry milk carton on which carmine (red colour extract from an insect) a food ingredient is mentioned. i want to know.

1- Is it confirmed carmine is obtained from an insect?

2- If any ingredient mix with the food which has no impact of taste and it just mix in a small ratio for colouring can make the food haram or not suitable for cosuming?

3- I have heared that carmine is only haram in hanafi madhab, is it true?

4- If above question is right, what should I do with the milk? Shall I through it away.

Drugs and Alcohol

Q: 

1. Alcohol is haraam and prohibited in Islam due to the fact that after having it, a person loses his senses and can not remember what he is doing and also you can get addicted to alcohol. My question is that if someone uses alcohol only for socialising, if he has a  few sips will it be fine or not?

2. There are some drugs which only boost your energy but you remain in your senses, such as cocaine and some other drugs. How does Islam differentiate between them. You remain in your senses but its not alcohol. Red bull drink also boosts the energy. Please explain. 

Rennet
