One of our friend started a business in pharmaceutical industry and he told us that imported medicines which Pakistani people are taking as granted had lot of beef and pork ingredients. Well I don't know where to draw a line for haraam as sometimes you have to take medicines.
And I saw a documentary on channel 8 about Saudi Arabia they mentioned in that documentary that vanilla is not halaal as it has alcohol in it and they told the saudi government but Since King or Shah wanted to eat it so they start selling in KSA. So yes we cannot take anything as granted we have to make sure. My mom used to eat vitamins and all of them have gelatin so now when we made her realize she stopped eating them.
