Will Voyager 1 eventually slow down/stop due to drag caused by gas and dust in interstellar space?

I was reading about Voyager 1 today, and found out that it is quite close to leaving the heliosphere, after which it will come into contact with interstellar gasses. Is this likely to slow it down? Or even stop it?

1. interstellar gas is almost non existent (a few atoms per meter)  so there is very little matter to actually interact with.  Think of the mass of these few atoms vs the entire mass of voyager - many orders of magnitude different. 

2. If you mean slow it down relative to its current direction of travel something would have to act on it fairly significantly for this to happen (eg run into a planet/stars gravity)  it wouldn't stop, its velocity would be changed in either direction or magnitude by this.
