Pipe tobacco is cleaner yes and you are not supposed to inhale the smoke. Although if you are coming from cigarettes you will inhale for a while till you get used to the pipe.
Tobacco with artificial flavoring is not clean though; none of those aromatic tobaccos are any cleaner than a cigarette. Buy real tobacco if you want clean.
Beginning smoking pipe you will need a few pipes, tobacco, tamper, cleaner, a case and whatnot but eventually it's cheaper.
And if you can buy bulk, it's gonna be much cheaper.
