Ramadhaan & Fasting

Taking sublingual tablets to quit drugs

Q: I would like to ask a question regarding Fasting (Sawm) and taking a sublingual tablets to quit drugs. The question is as follows:

May I fast if I take a sublingual tablet in the morning after suhur? The sublingual tablets name is Subutex 2mg it reduces cravings for opium
users. I would really like to fast. I would just like to know if is permissible for me for I only need to take this tablet for 7 consecutive days.

Sunnah I'tikaaf

Q: I have a question about i'tikaf. If we start itikaf on the night of the 21st there is a risk that we only complete nine nights (if Ramadan turns out to be 29 days). Will the sunnah still be fulfilled in this case? Or should we start the itikaf at the night of the 20th in order to make sure that we do at least 10 nights?

Kaffarah for fasting

Q: Can you please clarify the following. If some one did not fast at all in ramdhan without any valid reason, do they have to give kaffara for all the fasts, which would be 60x30(1800 rozas), which means they have to fast continuesly for at least 5 years? If they did that for five Ramdhans that means they have to fast for at least 25 years nonstop. How is it possible for anyone to be able to do that or even feed that many poor people? I am asking this because in my teenage years, after becoming baligh, I did not fast. I am very ashamed of that and I am now doing all the qazas of those years and I have nearly completed all my fasts. But I'm very worried about the kaffara, because I know I will never be able to fast nonstop for 25 years nor will I be able to feed so many poor people. I will however, be able to give 1.5kg wheat for each fast or equal amount of money. So is it possible for me to do that? Please give clear answer.
