In the last two decades, many hadronic resonances were discovered which are incompatible with the theoretical framework describing conventional mesons and baryons. Among these is the $\chi_{c1}(3872)$, a suspected tetraquark state, first observed in decays of $B$ hadrons into $\rm J/ \psi \pi^+ \pi^-$. The hadronic medium produced in high multiplicity $pp$ collisions allows us to study the onset of nuclear effects on these hadrons, and can thus help us to unveil more about the nature of the $\chi_{c1}(3872)$. The common decay channel with that of a conventional charmonium state $\psi (2\rm S)$ makes the latter an excellent reference for such studies, as we know more about its phenomenology. This talk discusses the recent preliminary results from LHCb on the measurement of the relative suppression of $\chi_{c1}(3872)$ over $\psi (2\rm S)$ exploring their shared $\rm J/ \psi \pi^+ \pi^-$ decay channel in $pp$ collisions at $\sqrt{s} = 8 \text{ TeV}$.
